TrinaSolar Launches World's First 800w+ Tandem Module

TrinaSolar, a global pioneer in smart photovoltaic (PV) and energy storage technologies, has achieved a significant industry milestone with the development of the world’s first industrial-grade solar module to surpass 800 watts of output. This cutting-edge 3.1 square meter panel is powered by 210mm x 105mm perovskite/silicon tandem cells and has been independently verified to deliver 808W of peak power by TÜV SÜD, a respected global testing and certification authority.

“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 perovskite/silicon tandem solar module with a 210mm industrial-standard size is a significant step toward the industrialization of tandem modules. This achievement also reinforces TrinaSolar’s leadership in PV innovation.”

Breaking the Limits of Traditional Solar Technology

As traditional silicon-based solar cells approach their maximum theoretical efficiency, the need for next-generation solutions has grown more urgent. Perovskite/silicon tandem technology is emerging as a game-changing alternative, with potential efficiencies reaching up to 43%—far beyond the capabilities of silicon alone. This innovation marks a fundamental evolution in solar energy, setting the stage for a shift toward more advanced, high-efficiency tandem cells as the new industry standard.

A Decade of Research and Innovation

TrinaSolar’s breakthrough is the result of more than a decade of sustained investment in research and development. The company has taken a leading role in advancing perovskite tandem technology, working alongside leading academic institutions such as Nanjing University, Jiangsu Province, and the Chinese Academy of Sciences. Over the years, Trinasolar has spearheaded numerous national R&D projects, filed over 330 patents in this field, and made significant strides in areas like perovskite bulk doping, interface optimization, and composite layer design, laying the groundwork for scalable, industrial-level production of tandem solar modules.

A Vision for a Cleaner, Brighter Future

Driven by its mission of delivering “Solar Energy for All,” TrinaSolar remains committed to accelerating the global energy transition. By pushing the boundaries of technological innovation, the company aims to support a more sustainable future and contribute meaningfully to the achievement of global net-zero goals.
