Passivation Effect of CsPbBr3 Films Based on SnBr4 Post-Treatment
Source abstract
Abstract
The defect state and energy level matching in CsPbBr 3 perovskite solar cells (PSCs) are the main factors affecting the photoelectric conversion efficiency (PCE). In this work, we report a synergic post-treatment strategy based on SnBr 4 to simultaneously modulate the defect state and energy level arrangement, which can effectively suppress the charge recombination loss and reduce the barrier of interfacial charge extraction. Consequently, the carrier transport properties of the CsPbBr 3 PSCs are significantly improved. The all-inorganic CsPbBr 3 carbon-based PSCs without a hole transport layer optimized with SnBr 4 have achieved a champion efficiency of 8.29%, which increases larger by 33% in average.
