A literature overview of cell layer materials for perovskite solar cells

We carefully analyzed over a hundred scholarly articles on the different layers of Perovskite solar cells (PSCs) and summarized the best material choices. The optimal materials for the perovskite layer are methylammonium and formamidine compounds. In terms of the electron transport layer, organic compounds like Fullerene and inorganic compounds such as metal oxides (TiO 2 , SnO 2 , ZnO) demonstrate superior performance. As for the hole transport layer, the options include Spiro-OMeTAD and its derivatives, known for their small organic molecular structure, PTAA as a representative polymer material, and inorganic materials like Cu 2 O, NiO, and CuSCN. Our goal in undertaking this task is to provide a valuable reference point for researchers exploring material choices for the distinct layers of PSCs. Graphical abstract
