How antisolvent miscibility affects perovskite film wrinkling and photovoltaic properties

Perovskite morphology dictates carriers’ behaviors and defect states, and thus the ultimate performance of the material. Here, the authors investigate micro-wrinkle formation in film by varying composition and deposition condition, and further implement the optimized structure for solar cells, achie...

Sumario:Perovskite morphology dictates carriers’ behaviors and defect states, and thus the ultimate performance of the material. Here, the authors investigate micro-wrinkle formation in film by varying composition and deposition condition, and further implement the optimized structure for solar cells, achieving 23% efficiency.
