英文摘要	A simple chemical process was developed in a scalable manner, to reduce trap states in perovskite absorbers from the very beginning. The obvious decrease of I-2 in methylammonium iodide and the decrease of trap density in the resultant films were identified, which led to the power conversion efficiency (PCE) of perovskite solar cells (PSCs) increase from 16.5% to 18.5%.; National Key Research and Development Program of China [2016YFB0700700]; National Natural Science Foundation of China [51672008, 51673025]; Young Talent Thousand Program; Enli Technology Co., Ltd.; SCI(E); ARTICLE; 76; 10548-10551; 53
