چکیده انگلیسی
- Dissolution-crystallization-dissolution process has been used to construct high quality CH3NH3PbI3 film.
- A best and repeatable PCE of 14.87% for CH3NH3PbI3-based solar cells has been achieved.
- Excellent stability for the CH3NH3PbI3-based device has been achieved.
High quality CH3NH3PbI3 films have been successfully constructed by two-step method, using the PbI2 solution after dissolution-crystallization-dissolution treatment. Depending on the dense perovskite thin film morphology, a best and repeatable power conversion efficiency of 14.87% was achieved from the CH3NH3PbI3-based solar cells. Furtherly, excellent device stability was also exhibited, which was remained at more than 77% efficiency under 50% humidity for 10 days.
