英文摘要	control of the morphology and coverage of high-quality perovskite films is the main issue affecting planar-structured perovskite solar cells fabricated by solution processing. in this work, the solvent engineering of mixed solutions for spin-coating uniform perovskite thin films was investigated in detail by adding different ratios of n,n-dimethylformamide (dmf) or gamma-butyrolactone (gbl) to dimethyl sulfoxide (dmso). the morphology and film thickness of the resulting perovskite films were found to be significantly altered. at 20%similar to 40% (volume fraction) of n,n-dimethylformamide mixed with dmso, micrometer scale grains and reduced grain boundaries were observed on the highly uniform perovskite thin films. the optimized planar-structured perovskite solar cells showed power conversion efficiency as high as 16.5% and a stabilized efficiency of 14.4% at a fixed forward bias of 0.88 v.
