Today, Trina Solar’s National Key Laboratory of Photovoltaic Science and Technology announced a significant achievement in the field of solar energy. The laboratory has developed the world’s first industrial-standard photovoltaic module featuring a peak power output of 808W using a 210 large-size perovskite/silicon tandem solar cell configuration, which has been certified by TÜV SÜD. This breakthrough represents a new world record, marking a pivotal moment for perovskite/silicon tandem technology.
Trina Solar has been actively engaged in the research and development of perovskite tandem technology since 2014. The company has led several projects in collaboration with renowned institutions such as Nanjing University, Nankai University, North China Electric Power University, and the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences, funded by Jiangsu Province’s technology support initiatives. In 2019, Trina Solar contributed to the national key project focused on the design, fabrication, and mechanism research of perovskite/silicon tandem solar cells.
To date, the company has filed a total of 331 patents in the field of perovskite tandem technology. Innovations have included methods to improve conversion efficiency through perovskite phase doping, interface treatments, and the design of composite layer structures. This decade-long effort has positioned Trina Solar at the forefront of the perovskite/silicon tandem solar cell industry.
As the efficiency of traditional silicon solar cells approaches its limits, the development of more efficient tandem cells has become a focal point for the industry. Perovskite tandem technology offers the potential to surpass the physical efficiency limits of single-junction cells, theoretically reaching an efficiency of 43%. To achieve over 35% efficiency in the commercialization of photovoltaic modules, the perovskite tandem technology is seen as a crucial solution.
Trina Solar’s advancements in perovskite/silicon tandem technology are viewed as a historic leap from traditional silicon-based cells to the next generation of tandem cells, paving new pathways for sustainable development. “This is a major breakthrough for perovskite/silicon tandem solar cell products and a key milestone in the advancement of photovoltaic technology towards the future,” said Gao Jifan, Chairman and CEO of Trina Solar and Director of the National Key Laboratory of Photovoltaic Science and Technology. “The successful development of the world’s first 210 standard industrial size 800W+ perovskite/silicon tandem solar cell module signifies that our company has taken a significant step towards the industrialization of tandem modules, further solidifying Trina Solar’s leadership in next-generation photovoltaic technology.”
