Abstract:
PbI2 heterogeneous-cap-induced crystallization with a face-to-face configuration is proposed to obtain efficient CH3NH3PbI3 perovskite films during thermal annealing. The films with large-size and dominative (110)-oriented grains can effectively boost the photovoltaic performance of the perovskite solar cells.
