  • World Record Set For Silicon Solar Module With Perovskite

    Persistent innovation in the global solar industry has led to new efficiency records being set for solar modules made with triple III-V germanium cells and tandem perovskite-silicon cells. The Fraunhofer Institute for Solar Energy Systems in Germany reported a record 34.2% conversion efficiency for a module made of triple III-V germanium cells, achieved through a new technique connecting cells directly to each other. Chinese firm Trinasolar also set a world record with a 29.2% conversion efficiency for its tandem perovskite-silicon solar module. California-based Tandem PV is making strides in the field as well, with their perovskite-silicon solar panels reaching 29.7% efficiency. The market is demanding higher performance and domestic capability in solar energy solutions, with companies like Tandem launching demonstration factories to produce high-power density, durable, and cost-effective solar panels.

  • Fraunhofer ISE achieves 34.4 efficiency for III-V germanium solar module

    Germany's Fraunhofer Institute for Solar Energy Systems ISE has set a new record for power conversion efficiency of its III-V germanium solar module, increasing it from 34.2% to 34.4% using "shingle-matrix" technology and space-grade solar cells. This achievement was made possible by adapting triple-junction solar cell technology to the terrestrial solar spectrum and utilizing anti-reflective front glass structures supplied by Temicon. The key factor in this breakthrough was the use of shingle-matrix technology for interconnecting the solar cells, eliminating solder-coated copper ribbons, reducing shading, and increasing active area utilization. In addition, in July 2025, Fraunhofer ISE achieved 40% efficiency for an indoor III-V solar cell based on an indium gallium phosphide absorber, showcasing their commitment to advancing solar energy technology for a more sustainable future.

  • All solar cell efficiencies at a glance – updated

    The Solar Cell Efficiency Tables, led by Professor Martin Green from UNSW, have been updated to Version 68 and will be available as open access in Joule starting from July 2026. The latest results show new efficiency records for large area silicon cells, modules, and lead halide perovskite cells. Progress has also been made with perovskite-silicon tandem cells and modules, indicating a positive trend towards more efficient and sustainable photovoltaic systems. Additionally, Version 67 presented a new record of 27.9% efficiency for an interdigitated-back-contact (IBC) device developed by Longi, showcasing significant advancements in solar cell technology since the tables were first published in 1993. Scientists from various institutions around the world, including the European Commission Joint Research Centre, Germany's Fraunhofer Institute for Solar Energy Systems, and the US National Renewable Energy Laboratory, have contributed to these advancements.

  • German consortium developing aluminum facade elements with integrated PV modules

    Researchers from Germany have developed a PV-activated design facade element with aluminum as the base material, funded by Germany's Federal Ministry for Economic Affairs and Energy. The approach involves directly laminating a PV module onto the aluminum facade element, with challenges such as bending and electrical insulation addressed. The prototypes of the PV-activated facade element differ from a facade element without PV by only two connectors, making them more likely to be accepted and used by installers. Scientists have developed a prototype called BIPV-4 for a façade element that utilizes aluminum-based PV technology, demonstrating that it can match conventional module performance while maintaining safe electrical isolation. The design includes rear junction boxes, insulated cross-connectors, a zigzag 3D structure, golden anodized aluminum, and optimized use of M12 cells. The group also created multiple PV design façade variants with adaptable cell formats, different surface geometries, and customizable color options, allowing for integration into diverse façade geometries and scalable to different module sizes up to 2 meters.
