Abstract
The internal absorption, charge recombination and internal quantum efficiency of lead iodide perovskite solar cells (PeSCs) based on CH3NH3PbI3 (MAPbI3) and HC(NH2)2PbI3 (FAPbI3) perovskites were investigated. The results show that FAPbI3 layer exhibits a wider internal absorption spectra than MAPbI3 layer, and FAPbI3 PeSCs possess lower charge recombination and higher charge collection efficiency due to the superior transport property of FAPbI3 perovskite, leading to higher internal quantum efficiency (IQE) than MAPbI3 PeSCs.320
