Abstract of Speech: Understanding and minimizing non-radiative recombination pathways is key to enhanced efficiencies in emerging solar cells, such as perovskite solar cells (PSC) and organic photovoltaics (OPV). Non-radiative recombination in any form, i.e. trap-assisted, or surface recombination of minority carriers at the (wrong) electrode will inevitably lead to lower efficiencies1. However, given the fast development of the efficiencies, the stability of OPVs is still not satisfactory. In this talk, I will focus on the charge transport layers (CTL) and their properties in increasing efficiency and stability. I will focus on the passivation of metal-oxides in nip-solar cells for OPVs. The criterion that the CTL is conducting2 will simultaneously lead to loss of selectivity.3 We have identified and mitigated an important loss-factor caused by ZnO in OPVs. Surface defects in ZnO cause n-doping in a thin layer close to the cathode, causing a loss of Jsc. By inserting a thin layer of SiOxNy from solution processing, the recombination zone will be removed, with increased efficiency and lifetime as a result.4 (1) Sandberg, O.

Biography of the Speaker：Dr. Bin Fan studied at the École Polytechnique Fédérale de Lausanne in Switzerland from 2007 to 2010 and founded Xiamen Weihua Solar Energy Co., Ltd. in 2010. His research mainly focuses on the field of perovskite solar cells, conducting systematic studies on material design, device physics, and large-scale manufacturing technology, aiming to address the core challenges in this field, such as photoelectric conversion efficiency, long-term stability, and commercial application. He has focused on key issues such as the regulation of perovskite crystal growth kinetics, the optimization of interface energy level matching, the precise passivation of defect states, and the large-scale amplification process. In terms of material system innovation, he has constructed wide bandgap perovskite materials through multi-cation/halogen component engineering and optimized the carrier transport path by combining gradient doping technology, achieving a coordinated improvement in device open-circuit voltage and fill factor. In the field of large-scale manufacturing, he has broken through the limitations of traditional spin-coating processes and established a crystallization control technology based on vacuum flash evaporation, achieving a full-size efficiency of over 19% for 2-square-meter modules (corresponding to an effective area conversion efficiency of over 21%). Through a systematic layout of the deep integration of basic research and industrial transformation, a complete R&D system covering key links such as material synthesis, device simulation, and process optimization has been established. Relying on the multi-dimensional R&D platform independently built, a multi-scale R&D test line covering from 0.01 cm² micro-devices to approximately 28,000 cm² large-area modules has been successfully established, achieving a full process connection from basic research to trial production amplification. This gradient technology development model effectively breaks through the bottleneck of converting laboratory achievements into large-scale production, accelerating the transformation process of perovskite photovoltaic technology from laboratory research to industrial application.
The 2025 Chinese Flexible and Printed Electronics Symposium
Speaker
Mikko Ritala
（ Doctor of University of Helsinki, Finland）
Abstract of Speech：Atomic Layer Deposition (ALD) is a method that offers the highest control in thin film deposition. ALD is based on alternate saturative surface reactions that are realized by pulsing precursor vapors on the substrate one at a time, separated by inert gas purging pulses. The saturative surface reactions make the film growth self-limiting, which gives ALD several unique features that render it superior compared to the competing techniques: conformality, large area uniformity (scalability), simple and accurate control of film thickness and composition at an atomic level, and reproducibility. ALD was invented in Finland already in 1974 by Dr Tuomo Suntola and coworkers for making flat panel electroluminescent displays, but the global breakthrough occurred at the turn of the Millennium when semiconductor industry recognized ALD as a key future manufacturing technology. Solar cells and optics are other current high volume manufacturing applications of ALD. The success of ALD is built on chemistry. The benefits of the technique can be exploited only when combinations of proper precursor compounds are found for each material of interest. In development of new precursors and processes, of the utmost importance is thorough knowledge of the chemistry of the processes. This presentation gives an overview of ALD chemistry research in University of Helsinki.

The 2025 Chinese Flexible and Printed Electronics Symposium
Speaker
Zijian Zheng
（ Professor of The Hong Kong Polytechnic University）
Abstract of Speech：The development of highly flexible energy storage devices such as supercapacitors and batteries are essential to the realization of fully flexible and wearable electronics. However, due to the instrinic limitation of materials, all commercial supercapacitors and batteries are rigid. While some recent studies demonstrated a wide range of flexible supercapacitors and batteries, the gain of flexibility is often at the cost of significant loss of energy density. In this talk, we will discuss the recent development of textile composite electrodes (TCEs), which possess textile-like flexibility and provide high energy density at the same time. We will elaborate the concept of TCE, the materials preparation, their versatility in different energy storage system, and their engineering toward high-performance energy storage devices. Finally, we will also discuss how to evaluate flexibility and energy density.

Speaker
Ziyi Ge
（ Professor of Ningbo Institute of Materials Technology & Engineering, Chinese Academy of Sciences）
Abstract of Speech：Perovskite solar cells (PSCs) are an emerging photovoltaic technology that has gained prominence in recent years. Among them, flexible perovskite solar cells (f-PSCs), characterized by high power conversion efficiency (PCE), lightweight, low-temperature processability, and inherent flexibility, demonstrate excellent application potential in fields such as building-integrated photovoltaics (BIPV), distributed power generation, and wearable electronics. This talk will systematically introduce the fundamental working principles, technological advantages, recent research advances, and commercialization potential of f-PSCs. First, a two-dimensional (2D) ferroelectric material (3P-yAI) was designed and synthesized to enhance exciton separation efficiency, achieving an inverted f-PSC with an efficiency of 23%. Subsequently, a series of cyano-derivatives were designed and synthesized to passivate grain boundary defects in the perovskite, release residual stress in the perovskite film, and enhance its flexibility, resulting in f-PSCs with an efficiency exceeding 24%. Furthermore, a zwitterionic elastomer was used to fill the perovskite grain boundaries, inducing and regulating nucleation and crystallization. The electrostatic interactions between the zwitterions enabled the creation of low-temperature, healable flexible films, leading to the fabrication of flexible perovskite solar cells with an efficiency of 24.5%. Most recently, by utilizing a buried self-assembled monolayer (SAM) interface with a large orientation angle design, the high-quality crystalline growth of the overlying perovskite was induced. This approach reduced defect density and released stress, achieving a flexible device efficiency of 25.05%, which represents the highest efficiency for a flexible perovskite solar cell publicly reported at the time.

Speaker
Jianxin Tang
（ Professor of Soochow University）
Abstract of Speech:Solution processing has emerged as an up-and-coming technique for the scalable manufacture of organic light-emitting diodes (OLEDs), owing to the material saving and compatibility with large-area manufacturing. Nonetheless, the development of solution-processable pure blue emitters that exhibit optimal color purity and electroluminescent efficiency presents a significant challenge in pursuing high-performance solution-processed devices. Herein, we demonstrate a molecular configuration strategy to create solution-processable multiresonance thermally activated delayed fluorescence (MR-TADF) emitters. The methodology encompasses the construction of a “Multiresonance-Donor-Multiresonance (MR-D-MR)” framework that features hybrid short/long-range charge-transfer excitation characteristics. The proof-of-concept emitter demonstrates considerable rigidity and reduced vibronic progression, resulting in pure blue narrowband emission at 474 nm. Furthermore, it possesses a large oscillator strength and significant spin-orbit couplings, facilitating rapid exciton dynamics. These advantageous properties enable the emitter to achieve a record-high electroluminescent efficiency of 35.1% for sensitizer-free solution-processed OLEDs.

Nicklas Anttu
（ Doctor of Åbo Akademi University）
Abstract of Speech: The diffraction of light in structures of size comparable to the wavelength of light allows to design and optimize the absorption of light. Thus, by choosing the geometry and materials of the structures, we can enhance the absorption of light, for example for solar cell and photodetector applications. Here, we discuss the possibilities of structuring the active semiconductor layer or adjacent processing layers for enhancing the absorption of sunlight in thin-film devices. Such structuring gives rise to varying types of absorption enhancement, including localized optical modes and light-trapping into the active layer by periodic and random structuring. Our work focuses on electromagnetic modelling of the scattering of light where we numerically solve for the Maxwell equations. We discuss also benefits and drawbacks of some of the main numerical methods for solving the Maxwell equations for such structured systems. The theoretical results are supplemented by experimental characterization of fabricated test structures.

Speaker
Yanming Sun
（ Professor of Beihang University）
Abstract of Speech: In recent years, with the rapid development of non-fullerene small molecule acceptors, the efficiency of organic solar cells has been continuously improved. However, small molecule acceptors have disadvantages, such as easy crystallization, poor photothermal stability and stretchability. In contrast, polymer acceptors can compensate for these shortcomings of small molecule acceptors. The all-polymer solar cells prepared have excellent stability and mechanical flexibility, showing great potential in wearable and flexible stretchable devices. The all-polymer system, with its high solution viscosity and good leveling performance, is very suitable for the preparation of large-area printed devices. Therefore, all-polymer solar cells have more advantages in commercial applications. Although the all-polymer system has many advantages, the research on all-polymer solar cells is relatively limited and the performance is relatively low. This report will systematically introduce the recent research progress of our research group in the field of all-polymer solar cells, including the design of high-performance polymer receptor materials, morphology control of all-polymer systems, device stability research, and green large-area processing.

Paola Vivo
（ Doctor of Tampere Universities, Finland）
Abstract of Speech: The rapid growth of the Internet of Things (IoT) has intensified concerns over battery dependence, raising environmental and economic challenges. This has driven interest in self-powered or battery-free devices. Indoor photovoltaics (IPVs) offer a sustainable solution by reducing battery waste. Among emerging materials for IPVs, low-toxicity perovskite-inspired materials (PIMs)—noted for their air stability and wide bandgaps (1.9–2.0 eV)—show promise, with theoretical indoor power conversion efficiencies of 50–60%. However, practical performance is limited by low-dimensional crystal structures and high defect densities that hinder charge transport. We recently developed a two-dimensional, triple A-site cation, antimony-based PIM, Cs₂.₄MA₀.₅FA₀.₁Sb₂I₈.₅Cl₀.₅ (CsMAFA-Sb), with a suitable bandgap for indoor light harvesting. Devices based on this absorber demonstrated record operational stability under ISOS L-1 and L-2 protocols. Through device engineering—including architecture screening, hole-transport layer optimization, and sulfonium-based interface passivation—we achieved a record 10.11% efficiency under 1000 lux white LED (6500 K). These devices also performed well under realistic low-light conditions (100–50 lux), marking a key step toward sustainable indoor energy harvesting.

（ Professor of Soochow University）
Abstract of Speech: Semiconducting colloidal quantum dots (QDs) have garnered great attention for photovoltaics due to their unique properties, including decoupled crystallization from film deposition, size-tunable bandgap, multiple exciton generation, etc. Nanometer-sized colloidal metal halide perovskite QDs have emerged and brought unique opportunities for photovoltaic application due to the high defect tolerance of perovskite and many features that emerge at the nanoscale. Perovskite QDs or more broadly, nanocrystals, show high photoluminescence (PL) quantum yields, spectrally tunable bandgap, flexible compositional control, and crystalline strain benefits. Metal halide perovskite QDs are readily synthesized with exceptional optoelectronic quality opening a route for next generation photovoltaic, as well as exploring LHP physics at the nanoscale.

Abstract of Speech: The inverse design of tailored organic molecules for specific optoelectronic devices of high complexity holds an enormous potential but has not yet been realized. Current models rely on large data sets that generally do not exist for specialized research fields. We demonstrate a closed-loop workflow that combines highthroughput synthesis of organic semiconductors to create large datasets and Bayesian optimization to discover new hole-transporting materials with tailored properties for solar cell applications. The predictive models were based on molecular descriptors that allowed us to link the structure of these materials to their performance. A series of high-performance molecules were identified from minimal suggestions and achieved up to 26.2% (certified 25.9%) power conversion efficiency in perovskite solar cells.

Abstract of Speech: Solution deposition from nanoparticle dispersions allows the use of eco-friendly processing agents such as alcohols or water for the fabrication of organic semiconductor thin-films for optoelectronic applications. Primary application of the eco-friendly device production from organic nanoparticles are solar cells where solvents are evaporated on large scale upon drying.

Abstract of Speech: Control over the intermolecular interaction as well as the molecular orientation of organic semiconductors with respect to the substrate plays a critical role in determining the performance of polymer solar cells (PSCs). In this talk, we will focus on the development of novel electron acceptors (M-series acceptors) based on ladder-type heteroheptacenes without sp3-hybridized carbons for efficient PSCs. A series of ladder-type heteroheptacene-based small molecules with branched or unbranched side chains flanked in different positions of their conjugated backbone, or with varied electron withdrawing end groups flanked on the same conjugated backbone, were designed and synthesized to investigate the effect of side-chains and end group on the crystallinity, molecular orientation, charge transport and photovoltaic properties of M-series acceptors. Furthermore, we report the effect of noncovalent intramolecular interactions and molecular weight on the power conversion efficiencies (PCEs) as well as stability of the acceptors. As results, the best-performance acceptor with optimized molecular orientation affords PCE approaching 20% which is the highest among all the A-D-A type nonfullerene acceptors reported to date.

Abstract of Speech: With the rapid development of the Internet of Things (IoT) and portable electronics, there is an increasingly urgent demand for distributed, low-power energy sources. Organic photovoltaics (OPV) technology, leveraging its flexibility, lightweight nature, solution processability, and exceptional photoelectric conversion capability under low-light conditions, has emerged as an ideal solution for micro-light energy harvesting. By utilizing the efficient absorption of OPV material systems for non-direct sunlight and artificial ambient light (such as indoor LED and fluorescent lighting), scattered light energy ranging from microwatt to milliwatt levels is converted into electrical power. Through the optimization of donor-acceptor material blend film morphology, the development of novel low-work-function interlayers, and the design of device structures tailored for 600-1000 lux illumination, the power conversion efficiency (PCE) and output voltage of OPV under low-light environments (200-1000 lux) have been significantly enhanced. The resulting ultra-thin, flexible OPV modules can be seamlessly integrated into various sensor nodes, electronic labels, and wearable devices, enabling continuous, maintenance-free autonomous energy supply. This eliminates reliance on traditional batteries and provides critical technical support for building large-scale, self-powered IoT ecosystems.

Abstract of Speech: Tactile perception is one of the core components of artificial intelligence (AI). Simulating human perception through electronic means has long been a major challenge in the AI field. Compared with the relatively mature bionic research on micro/nano sensors for several senses (sight, hearing, smell, and taste), bionic tactile perception remains an unsolved problem. To address the limitations of traditional tactile sensor arrays, such as low integration and resolution, inability to balance high sensitivity with a wide linear response, and poor flexible extensibility, a strategy of detecting stress by regulating the structure-interface-energy band of low-dimensional semiconductors is proposed to conduct comprehensive research on the entire tactile sensing chain, and AI machine tactile perception was successfully constructed. Specifically, to tackle low integration and resolution, a ZnO nanowire array was innovatively built, and its luminescent properties were used to detect stress, resulting in a world-leading tactile sensing array with 10-million-level pixel integration and an ultra-high resolution of 2 μm. To resolve issues related to sensitivity and linear detection range, a micro-scale ultra-thin composite stretchable sensing material was developed, and the intrinsic relationship between multi-level structure-mechanics-system strain was clarified, enabling flexible tactile sensing of multiple physical quantities with a wide linear response and ultra-high sensitivity of 389 dB. Furthermore, precise control of micro-movements and tactile perception were achieved, which were successfully integrated into intelligent prostheses and robots to enables accurate and controllable grasping of objects, endowing robots with tactile sensing capabilities.

Martti Toivakka
（ Doctor of Åbo Akademi University）
Abstract of Speech: Mass-produced paper electronics (large-area printed electronics on paper substrates) hold promise for flexible, low-cost applications in everyday life. Obvious attractions of using paper for printed electronics and functionality include the low cost and the large existing product base that can potentially benefit from added functionality. These, combined with biodegradability and ease of disposal through either fiber recycling or incineration have been put forward as motivators for research into one-time use (“throw-away”) paper-based electronics. Yet, paper was not designed for electronics. Its high surface roughness and porosity, complex chemistry, structural irregularity, and poor dimensional stability under humidity pose challenges. These limitations require modifications to both paper substrates and electronic component architectures to enable functional devices. Compared with plastic substrates commonly used in printed electronics, paper provides notable benefits. Its surface properties can be engineered to optimize ink printability, similar to treatments used in traditional printing (e.g., offset or rotogravure). By controlling surface porosity and energy, print resolution improves, coffee-ring effects are minimized, and adhesion is enhanced. In addition, mineral pigment-coated papers withstand higher temperatures than low-cost plastics, enabling low-cost infrared sintering of metal inks. This presentation introduces paper electronics, examines how paper properties affect device performance, and highlights laboratory-scale demonstrator devices.

Abstract of Speech: With the rapid development of human-computer interaction (HCI), there is an urgent need to construct flexible bionic perception systems with sensory and learning capabilities. However, endowing bionic perception systems with a high level of intelligence remains a key challenge in their current development. Inspired by biological perception systems, researchers have developed a bionic perception system capable of signal sensing, transmission, and processing as a proof of concept, which can effectively enhance information processing capabilities. Meanwhile, as signal acquisition units, sensors can also be used for biological signal monitoring. Therefore, starting from the construction of human-computer interaction systems, this report will elaborate on the research progress of flexible sensors in building bionic perception systems, human-computer interaction systems, and rehabilitation medicine fields, while combining the potential of bioelectric sensing in lumbar health monitoring and MRI/CT-compatible EEG acquisition.

Abstract of Speech: As a class of functional materials with "intelligent" behaviors, dynamic responsive smart materials can undergo specific structural isomerization changes in response to external environmental stimuli such as light, heat, electricity, and pH values, etc., thereby altering their physical and chemical properties. These materials exhibit extremely broad application prospects in fields such as sensors, optoelectronic devices, robots, and information storage. In this report, the presenter leverages the orthogonality between coordination bonds and other non-covalent interactions to develop a hierarchical self-assembly strategy for supramolecular frameworks, with coordination bonds as the core driving force. This strategy is applied to the precise construction of dynamic responsive smart material systems, and the presenter also explores the applications of these materials in areas such as energy conversion and supramolecular catalysis.

Pengfei Song
（ Associate Professor of Xi'an Jiaotong-Liverpool University）
Abstract of Speech: In the context of rapid advancements in analytical science and instrumentation, traditional detection methods (e.g., ELISA) suffer from complex operation, reliance on professionals, and expensive equipment, while paper-based microfluidic technology (μPADs), despite being low-cost and easy to fabricate, faces challenges such as poor reproducibility and low efficiency. To address these issues, we propose several innovative solutions: ​First, by leveraging deep learning-assisted smartphone detection with the GoogLeNet algorithm, we eliminate environmental light interference, significantly improving the accuracy of paper-based colorimetric ELISA (AUC improvement of 4%) and enabling a "image input–result output" cloud transmission mode. ​Second, we develop a fully automated paper-based microfluidic platform featuring a mechanical rotary valve structure, achieving rapid Alzheimer’s disease screening (results in 20 minutes) with clinical sample performance matching commercial kits. ​Third, we construct an offline smartphone detection system using a YOLOv5-based standalone app that eliminates cloud computing dependencies, demonstrating 97% accuracy in Aβ peptide detection. Additionally, this technology is extended to multiplex biomarker analysis (e.g., cardiac markers), completing the detection of three markers within 30 minutes and showcasing strong commercialization potential. By integrating microfluidics, artificial intelligence, and portable devices, these innovations provide ​low-cost, high-reliability solutions for precision medicine and on-site diagnostics.
