- September 09, 2025: Milestone in Flexible Perovskite Solar Cells: EU-funded PEARL Consortium Demonstrates Roll-to-Roll Production
At month 18 of its three-year Horizon Europe project, the PEARL consortium has made decisive progress toward its target of 25% efficient, low-cost flexible perovskite solar cells with carbon electrodes. By combining cutting-edge materials research, pilot-scale roll-to-roll (R2R) manufacturing and comprehensive sustainability measures, partners across Europe have delivered a series of significant achievements. - November 06, 2024: Innovative layer systems for sustainable photovoltaic solutions in the building sector
In the construction and building sector, sustainable solutions for reducing energy requirements and improving the carbon footprint are more in demand than ever. In view of rising energy prices and strict regulations for lower energy consumption in buildings, innovative technologies such as perovskite and organic solar cells offer great potential. However, the cost, durability and efficiency of these solar cells pose a major challenge. As part of the EU-funded PEARL and BOOSTER projects, the Fraunhofer FEP is developing new coating and process technologies that will significantly increase the durability and efficiency of solar cells and sustainably reduce costs and material requirements. At the BAU 2025 trade fair, Fraunhofer FEP will be presenting a number of pioneering technologies and demonstrating their potential applications in the construction and building sector from January 13 to 17, 2025 at the joint Fraunhofer booth in Hall C2, Booth 528. - August 07, 2024: Revolutionizing Solar Energy: EU’s PEARL Project Targets Next-Gen Flexible Perovskite Solar Cells
Current perovskite solar cells face significant challenges in stability and durability, hindering their long-term application. To address these issues, the European Union has launched the innovative PEARL project, which aims to enhance perovskite solar cells with cutting-edge carbon electrodes. This EU-funded initiative aspires to significantly improve the efficiency, stability, and cost-effectiveness of these solar cells, targeting efficiencies of over 25% and substantially lower production costs. PEARL represents a major step forward in making sustainable solar power more accessible and reliable.
