Modulated CH(3)NH(3)PbI(3−x)Br(x) film for efficient perovskite solar cells exceeding 18%

The organic-inorganic lead halide perovskite layer is a crucial factor for the high performance perovskite solar cell (PSC). We introduce CH(3)NH(3)Br in the precursor solution to prepare CH(3)NH(3)PbI(3−x)Br(x) hybrid perovskite, and an uniform perovskite layer with improved crystallinity and appar...

description The organic-inorganic lead halide perovskite layer is a crucial factor for the high performance perovskite solar cell (PSC). We introduce CH(3)NH(3)Br in the precursor solution to prepare CH(3)NH(3)PbI(3−x)Br(x) hybrid perovskite, and an uniform perovskite layer with improved crystallinity and apparent grain contour is obtained, resulting in the significant improvement of photovoltaic performance of PSCs. The effects of CH(3)NH(3)Br on the perovskite morphology, crystallinity, absorption property, charge carrier dynamics and device characteristics are discussed, and the improvement of open circuit voltage of the device depended on Br doping is confirmed. Based on above, the device based on CH(3)NH(3)PbI(2.86)Br(0.14) exhibits a champion power conversion efficiency (PCE) of 18.02%. This study represents an efficient method for high-performance perovskite solar cell by modulating CH(3)NH(3)PbI(3−x)Br(x) film.
