Trinasolar has announced that it has developed the world’s first industrial-standard solar PV module delivering a maximum power of over 800W. The 3.1m2 module, produced with 210mm x 105mm perovskite/silicon tandem solar cells, has achieved a peak power output of 808W, certified by TÜV SÜD.
“This is a monumental breakthrough for perovskite/silicon tandem solar modules and a key milestone in PV technology,” commented Trina Chairman and CEO Gao Jifan.
“The successful development of the world’s first 808W perovskite/silicon tandem solar module with a 210mm industrial-standard size is a significant step toward the industrialization of tandem modules, the achievement also reinforcing Trinasolar’s leadership in PV innovation.”
As conventional silicon-based solar cell efficiency nears its theoretical limit, high-efficiency tandem cells have attracted increasing attention. Perovskite tandem technology has the potential to exceed existing limitations, with theoretical efficiencies reaching up to 43%. As a transformative solution for next-generation solar energy, perovskite/silicon tandem technology is poised to become the new industry standard, signalling an historic shift from silicon-based to tandem solar cells and ushering in a new era of sustainable development.
Over the past decade, Trinasolar has been a pioneer in perovskite tandem cell technology. In collaboration with universities including Nanjing University and the Chinese Academy of Sciences, the company has led numerous national research projects and filed 331 patents related to tandem technology, significantly improving conversion efficiencies through advances in perovskite bulk doping, interface engineering and composite layer design.
