Název v původním jazyce

Controlled growth of large grains in CH3NH3PbI3 perovskite films mediated by an intermediate liquid phase without an antisolvent for efficient solar cells

Popis výsledku v původním jazyce

Large grains with uniform morphologies of the perovskite films are important for stable, high-performance perovskite solar cells. Herein, an effective strategy to control the growth of large grains in the CH3NH3PbI3 perovskite films is demonstrated by forming an intermediate CH3NH3PbI3·methylammonium chloride (MACl)·xCH3NH2 liquid phase induced by CH3NH2 gas treatment in combination with a MACl additive without an antisolvent. This intermediate liquid phase enables the well-controlled growth of large grains up to 3 μm, highly uniform morphology, and higher crystallinity in the final CH3NH3PbI3 perovskite films. The high-quality CH3NH3PbI3 film derived from the CH3NH3PbI3·MACl·xCH3NH2 phase leads to enhanced carrier lifetime and reduced charge-trap density and nonradiative recombination of the perovskite films. In addition, the defect healing and reduced grain boundaries also greatly improve the environmental stability in ambient air.n
