LUMINOSITY
Large area uniform industry compatible perovskite solar cell technology
LUMINOSITY is an industry-led project aimed at scaling up flexible perovskite solar cell (PSC) technology for commercial production. The goal is to demonstrate roll-to-roll (R2R) produced photovoltaic (PV) modules with power conversion efficiencies exceeding 20% over large areas (>900 cm²), bridging the gap between lab-scale and full-scale production, and reaching technology readiness level (TRL) 7.
A unique feature of this project is the use of an aluminum-based substrate with a fluorinated-tin-oxide (FTO) electrode, proprietary to HyET Solar, which enables high-quality processing without the temperature limitations of typical polymer foils. This allows for improved efficiency, stability, and environmental sustainability while maintaining flexibility. The consortium includes research groups, tech developers, equipment manufacturers, and industrial partners, working together to overcome key challenges and advance PSC technology for wider adoption.
Nexus
NEXt generation of sUstainable perovskite-Silicon tandem cells
NEXUS is a 3-year project funded by the European Commission under HORIZON EUROPE, aiming to develop 2-terminal perovskite-Si tandem solar cells with power conversion efficiencies over 33% (modules >30%) through an eco-design approach. This includes solvent-free perovskite deposition, sustainable material use, circularity, recyclability, and streamlined manufacturing for European commercialization.
NEXUS focuses on creating stable perovskite absorbers resistant to light, heat, and humidity, using eco-friendly methods. The project will develop low-impact technologies, efficient top cells, and deliver high-efficiency modules, along with a comprehensive Bill of Materials. Scalable processes and proof-of-concept equipment will be demonstrated, outdoor durability tested, and economic and environmental impacts assessed to guide sustainable R&D.
DIAMOND
Ultra-stable, highly efficient, low-cost perovskite photovoltaics with minimised environmental impact
The DIAMOND project aims to address four key challenges in perovskite PV commercialization: achieving higher efficiency than silicon PV, improving stability and lifetime, reducing manufacturing costs, and enhancing sustainability. The project targets efficiency levels of ≥27% for cells and ≥24% for modules, ultra-stable cells with a 5,000-hour lifetime, and scalable fully-printed modules. It also focuses on minimizing environmental impact with reduced lead content and recyclable designs. The expected outcomes include reducing technological risks, enabling integration in various applications, and lowering investment costs for PV factories. The project will promote EU industrial leadership, reduce PV costs, and support the transition to a climate-neutral economy by providing affordable, sustainable energy solutions.
PEARL
Flexible Perovskite Solar Cells with Carbon Electrodes
Incorporating carbon electrodes into perovskite solar cell (PSC) designs offers key benefits: reduced material costs, enhanced stability, streamlined fabrication, and lower emissions.
Thus, the primary objective of PEARL is to realize flexible perovskite solar cells processed with industrially viable, scalable and environmentally sound methods, showing long term operational stability surpassing the IEC standards, efficiency of > 25%, lowered production costs below 0.3 EUR/Wp and minimal emissions < 0.01 kg CO2eq/kWh.
To achieve its goals, PEARL is working on creating advanced solar cell designs that include simple, layered structures and innovative device layouts using carbon-based top electrodes that can be processed at low temperatures. This approach targets new markets such as building-integrated photovoltaics (BIPV), solar panels on vehicles (VIPV), and powering smart devices in the internet of things (IoT).
PILATUS
Digitalised pilot lines for silicon heterojunction tunnel interdigitated back contact solar cells and modules
PILATUS is a 3-year European project aiming at demonstrating 3 digitalised pilot lines for production of silicon wafers, solar cells, and modules. PILATUS will contribute to re-build a “Made in Europe”, leading-edge, and competitive PV industry, based on silicon heterojunction (SHJ) tunnel-interdigitated back contact (tunnel-IBC) PV technology with just 10 process steps for the cell production, with the entire value chain retained in Europe and compliant with the latest environmental standards. Main objectives are: to demonstrate the high-volume production of SHJ tunnel-IBC PV, to validate and pre-certify performance of PV cell and module, eco-design of tunnel-IBC PV modules and manufacturing lines and to demonstrate favourable cost/Wp of the SHJ-IBC modules.
VIPERLAB
Fully connected virtual and physical perovskite PV lab
Viperlab accelerated access to the best EU perovskite infrastructures and the use of advanced data mining approaches; It will stimulate European academic and industrial researchers to work together on next generation technology which will accelerate the perovskite PV technology development in Europe. State-of-the-art material synthesis and device design and development, as well as standardized testing and simulation methods, and databases are the main services offered to validate at lab-scale and at pre-industrial-scale, the technology that will form the backbone for EU PV recovered worldwide leadership all along the value chain. VIPERLAB will boost this ambition for the emerging perovskite community by providing transnational and virtual access aiming to: Combine European perovskite PV infrastructures to accelerate development and testing, providing access to EU academia and industry. Secondly, support the European perovskite community through resources and networking, and develop a database on materials, performance, and impacts to support evidence-based decisions.
TESTARE
Twinning for excellence in TEsting new generation PV: Long-term STAbility and field REliability
TESTARE is a Horizon Europe project that aims to stimulate excellence at the University of Cyprus (UCY) in the topic of new-generation PV technologies from the perspective of long-term stability and field reliability testing. TESTARE aims to improve the research and innovation (R&I) capabilities of the DegradationLab, a unit dedicated to studying the wear and failure of emerging solar devices. UCY will collaborate with top research institutions, including IMEC in Belgium, Fraunhofer Institute in Germany, and Ben-Gurion University in Israel. The project aims to improve DegradationLab’s research output, increase funding success, boost its reputation, strengthen partnerships with leading institutions and industry, enhance ties with Middle East and North Africa countries, and improve research management at UCY. Activities will include researcher exchanges, training, infrastructure sharing, PhD schools, and webinars.
