Trinasolar, a globally prominent manufacturer of smart PV and energy storage solutions, has developed the world’s first industrial-standard solar PV module delivering over 800W of maximum power. The 3.1 sq m module, produced with 210mm x 105mm perovskite/silicon tandem solar cells, has achieved peak power output of 808W, certified by the global testing, inspection and certifying body TÜV SÜD.
“This is a monumental breakthrough for perovskite/silicon tandem solar modules and a key milestone in PV technology,” said Gao Jifan, chairman and CEO of Trinasolar. “The successful development of the world’s first 808W with a 210mm industrial-standard size is a significant step toward the industrialisation of tandem modules.”
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 these limitations, with theoretical efficiencies reaching 43%. As a transformative solution for next-generation solar energy, the technology could become the new industry standard, signalling a historic shift from silicon-based solar cells to tandem solar cells, and ushering in a new era of sustainable development.
Over 10 years Trinasolar has been a pioneer in perovskite tandem cell technology. In collaboration with universities including Nanjing University, Jiangsu province and the Chinese Academy of Sciences, the company has led numerous national research projects and has filed 331 patents related to tandem technology, as well as significantly improved conversion efficiency through advances in perovskite bulk doping, interface engineering and composite layer design. This work has helped lay the foundation for the industrialisation of perovskite/silicon tandem modules.
