As a promising photovoltaic material, metal halide perovskite yields high efficiency in solar cells. However, the deep-level traps of minority carriers at the surface of the p-i-n perovskite solar cells can suppress nonradiative recombination. The precise passivation of deep-level traps has been a major focus in raising the power conversion efficiency (PCE) to the theoretical Shockley-Queisser limit.

Recently, a research group led by Prof. Xu Jixian and Prof. Wu Xiaojun from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), and their collaborators from Suzhou Institute …
