Research activities on perovskite solar cells in China

Abstract

Perovskite solar cells (PSCs) have attracted much attention because of their high efficiencies and low costs for production. Although academic research started late in China, compared to that in Europe and Korea, the majority of active PSC research is now conducted in China; furthermore, Chinese research groups currently hold the certified highest efficiency record for both an individual PSC and a PSC module. China is also the world’s largest supplier of solar modules, making it a promising country in which to realize the commercialization of PSCs. Herein, we review PSC research activities undertaken in China (both academic and industrial) and discuss significant remaining challenges to overcome for early commercialization of PSCs. We propose that research activities shift away from material and device structure development toward improving PSC stability and developing methods for large-area module fabrication. In addition, we suggest that a recognized certification center is urgently needed in China to further accelerate PSC research.
