Abstract

In two-step sequential deposition to prepare perovskite film, morphology of PbI₂ film plays a crucial effect on the as-prepared perovskite CH₃NH₃PbI₃ film. In this work, PbI₂ films are treated by antisolvents of diethyl ether (DE) and chlorobenzene (CB) respectively to adjust the perovskite CH₃NH₃PbI₃ formation. It is found that the DE treated corresponding perovskite film has smoother surface morphology and enhanced carrier transport property compared with the pristine perovskite film and the film treated by the CB. In a carbon based hole transport material (HTM)-free solar cell configuration, perovskite solar cell (PSC) assembled by the DE treated perovskite achieves the champion power conversion efficiency (PCE) of 11.91%, which is the highest compared with the pristine PSC of 9.07% and the CB treated PSC of 10.87%.
