A cell with a 200 nm MAPbI 3 perovskite absorber was chosen to study the effect of defect density at the absorber/ETL interface on the performance of HTL-free perovskite solar cells. Defect density at the interface of ZnO and MAPbI 3 was altered from 10 8 to 10 14 cm −3 while the other parameters are constant.
