This newsletter points out the interesting improvements in solar power technology. Dr. Stéphane Cros of CEA presented improvements from the Apolo European project and these improvements included record module efficiencies near 19% and understandings into laser scribing, deposition uniformity and encapsulation issues.
Dr. Emma Spooner, at the University of Manchester, intensely studies scalable semi-transparent organic photovoltaics (STOPVs) for windows and building-integrated PV. She collaborates with Contra Vision to develop remarkably revolutionary OPV stacks.
Lena Reinke of Panacol presents several highly effective adhesive solutions and these solutions considerably improve the durability and electrical reliability of a large number of flexible solar modules. Francesca Scuratti of Ribes Tech uses advanced roll-to-roll (R2R) additive manufacturing and organic photovoltaics to overcome several IoT2 challenges and enable energy independence.
Aldo Kingma of Solliance presented meaningful progress. This progress involved developing a pilot line for several cost-effective and flexible PV laminates, easing their smooth integration into buildings and infrastructure.

CEA | Apolo story for the manufacturing of record modules (11 cm2) close to 19% efficiency
Stephane Cros
In this talk, we will list the performances that CEA achieved in Apolo European project with flexible cells and modules. As compared to cells, module fabrication requests specific steps like large deposition uniformity or laser scribing. We will also highlight the importance of the stability and the challenges related to encapsulation. Dr Stéphane CROS has a PhD in the field of nanocomposite organic/inorganic materials (ESPCI, Paris, 2002 He joined the CEA in 2004, where he is in charge of stability/lifetime in the CEA-LCT laboratory (INES institute) making Perovskite and tandem Silicon/Perovskite solar cells. Senior Expert.
University of Manchester | Scalable Semi-transparent Organic Photovoltaics
Dr. Emma Spooner
Organic photovoltaics (OPVs) are an emerging thin film solar technology based on organic semiconductors. OPVs are promising due to their potential for solution processability, low temperature manufacture, and tuneable absorption. The latter of these allows for semi-transparent OPVs (STOPVs), meaning visible light can be transmitted whilst electricity is still generated. STOPVs have huge potential for building integrated PV, power generating windows, and other architectural and industrial applications. Here we will discuss our project based on scalable STOPVs, as part of a collaboration between the University of Manchester and Manchester based company Contra Vision. Work so far includes preliminary transfer-matrix modelling work evaluating different active layer components and top electrodes; dilute donor compositions for tuning light utilisation efficiency; and exploration of a variety of charge transport layers towards a fully printed OPV stack.
In this session, you will explore the following topics:
Semi-transparent OPVs - Explore optical layers such as dielectric Bragg reflectors and antireflective coatings that enhance performance.
Project Collaboration: Learn about the partnership with Contra Vision to develop flexible, semi-transparent OPVs that can be retrofitted.
Innovative Approach: Discover how all layers are optimized for performance, scalability, and transparency to create a fully printed OPV stack.
Join us on 22-23 October 2025 in Berlin, Germany, for Perovskite Connect—co-located with The Future of Electronics RESHAPED. This conference and exhibition bring together the global perovskite industry to discuss the latest technological advancements, commercial breakthroughs, and emerging collaborations. Stay ahead of the curve as new ideas, projects, and ecosystems take shape.

TNO partner in Solliance | Towards Mass Customizable PV
Aldo Kingma
For over 11 years, (TNO part of) Solliance has been dedicated to the effort of enabling low-cost production of customized solar modules suitable for integration into buildings, infrastructure, or any surface exposed to solar irradiation. During this time we have established significant expertise in the optimization of flexible PV laminates for integration into various products, using low-cost materials while still obtaining the desired lifetime. Currently, we are applying this expertise in the development of a Mass Customization pilot line, which will enable large scale production of customized PV laminates suitable for integration. Mass Customization will allow flexibility in electrical output, material choice, lifetime, flexibility and aesthetics at minimum cost, and thus make the integration of PV materials more cost effective.
You'll will explore the following topics:
Mass Customization- Motivation, Goals, Challenges
Reliability research-Materials and architecture, Processing, Application specific testing
