Abstract:
In the present work, we proposed an improved two‐step deposition method by optimizing the reaction temperature and the dipping time for the fabrication of perovskite films. The perovskite film fabricated at 70 C exhibits a full surface coverage and a smooth uniform crystal morphology with a particle size up to micrometer scale. The corresponding inverted perovskite solar cell with a structure of ITO/poly(3,4‐ethylenedioxythiophene): poly(styrene‐sulfonate)(PEDOT:PSS)/CH 3 NH 3 PbI 3 /C 60 /2,9‐dimethyl‐4,7‐diphenyl‐1,10‐phenanthroline (BCP)/Ag displayed a higher power conversion efficiency (PCE) of 13.6% than that of the device fabricated at 20 C (8.06%), as well as the high reproducibility. The small but meaningful modification for two‐step deposition would provide an efficient and convenient way to optimize planar perovskite solar cells and facilitate the potential applications of perovskite solar cells more widely.
