sOlaR cells n- Type polymer layers enable efficient, scalable, and thermally stable perovskite solar modules Danpeng Gao1†, Jie Gong1†, Lei Yang1†, Ning Wang1, Bohong Chang1, Liangchen Qian1, Francesco Vanin1, Chunlei Zhang1, Zexin Yu1, Shuai Li1, Jianqiu Gong1, Zonglong Zhu1,2,3,4,5* Fullerene- based electron transport layers (ETls) used in inverted (p- i- n) perovskite solar cells face issues regarding cost, scalability, and instability, whereas highly stable inorganic oxides feature unfavorable energy alignment and enhance hysteresis, which reduce power conversion efficiency (PCE). We report a nonfullerene conjugated polymer, 2PB- T, that incorporates coplanar and electron- withdrawing perylene bisimide (PBI) units into its backbone. …
