Professor Liyuan Han and his team 

Chinese scientists have successfully fabricated the large-area perovskite films, an important step for achieving cheaper solar power generation, China News reported on Sept. 11.

The research achievement made by Professor Liyuan Han’s team at the School of Materials Science and Engineering, Shanghai Jiao Tong University, has recently been published in the international academic journal of Nature.

Silicon materials are commonly used nowadays in producing photoelectric materials for solar cells. Despite high conversion efficiency, fabricating the materials is costly, and a lot of chemical substances used in the process can harm the environment.

Han said his team spent three years developing the film, which increases the conversion efficiency of the perovskite solar cells and lowers fabricating costs.

Han added that the method of fabricating the large-area perovskite films provided a new development direction for mass production of the perovskite solar modules.

As for the next step, Han disclosed that his team will delve into the stability of perovskite solar cells to accelerate commercialization. The team hopes to lower power generation costs and alleviate energy crises together with other science researchers.
