Trinasolar announced it has developed an “industrial-standard” solar panel that reaches 800 W. The 3.1 m2 module using 210×105-mm perovskite/silicon tandem solar cells reached 808 W and was certified by inspection body TÜV SÜD. The rectangular cell (essentially a half-cut G12 wafer) layers silicon and perovskites to exceed conventional efficiency ratings.
“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.
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 up to 43%. As a transformative solution for next-generation solar energy, perovskite/silicon tandem technology is poised to become the new industry standard, signaling a historic shift from silicon-based solar cells to tandem solar cells and ushering in a new era of sustainable development.
Trinasolar has invested over 10 years into perovskite tandem cell R&D. In collaboration with universities including Nanjing University, Jiangsu province and the Chinese Academy of Sciences, the company has led national research projects in this domain. The company has filed 331 patents related to tandem technology and has improved conversion efficiency through advances in perovskite bulk doping, interface engineering and composite layer design. This work has laid the foundation for the industrialization of perovskite/silicon tandem modules.
