Abstract

Perovskite/Organic Tandem Solar Cells In article number 2204347, Tingting Shi, Hin-Lap Yip, Man-Keung Fung, Yue-Min Xie, and co-workers aim to minimize the energy loss of perovskite/organic tandem solar cells (POTSCs) induced by compromised wide-bandgap perovskite sub-cells. An ionic liquid, methylammonium formate, is proposed to engineer the top and bottom all-inorganic perovskite (CsPbI2Br) interfaces, which leads to passivated perovskite interfacial defects with reconstructed surfaces, therefore, high-efficiency POTSCs are obtained.
