Leader in perovskite/crystalline silicon tandem photovoltaic cells
Beijing Yaoneng Technology Co., Ltd. was registered in Beijing (Haidian) Overseas Students Pioneer Park in 2017, and has obtained the Zhongguancun high-tech enterprise qualification. The main business belongs to the field of new energy materials, and the research and development products are devices, processes and materials for perovskite/crystalline silicon tandem solar cells and modules. It is the earliest domestic enterprise dedicated to the industrialization of perovskite crystalline silicon tandem solar cells.
Perovskite/crystalline silicon tandem photovoltaic cells
It is a structure upgraded from a traditional crystalline silicon single junction (single semiconductor material) battery to a tandem battery (two semiconductor materials in series). It can break through the original efficiency limit, thereby greatly reducing the overall cost of power generation.
Breaking through the theoretical limit of a single material, the theoretical efficiency of perovskite/crystalline silicon tandem photovoltaic cells is as high as 42.5%. In addition , perovskite can be combined with HJT, TOPCon, or PERC cells to form tandem cells to realize the upgrade of the existing photovoltaic industry.
7 years
Since the publication of Science results breaking the single-junction world record in 2014, he has been focusing on the development of the stacking technology route for 7 years, increasing the conversion efficiency by more than 1% (absolute value) per year on average.
100+ articles
The core technical team of the project has published more than 100 papers in the field of perovskite solar cells, including more than 70 papers in top SCI journals such as Science, Joule, and Nature Energy.
27% efficiency
The highest photoelectric conversion efficiency of small-area single-junction perovskite solar cells developed by the team exceeds nearly 25% (the world record is 25.5%), the efficiency of small-area perovskite/crystalline silicon tandem cells exceeds 27%, and the accelerated aging life exceeds 2000 hours , at the international and domestic advanced leading level.
11000+ times
The founders of the team are all from Tsinghua University and Peking University. The core R&D team members all graduated from the top 100 universities at home and abroad. The total number of citations of the team members' papers has reached more than 11,000 times, and the average personal citation H-index is 23.
