摘要

该文通过多步旋涂法制备基于不同PbBr₂浓度的CsPbBr₃太阳电池。研究不同PbBr₂浓度对CsPbBr₃太阳电池光伏性能的影响。结果表明,相比于0.6、0.8和1.2 mol/L PbBr₂浓度的CsPbBr₃太阳电池,1.0 mol/L PbBr₂浓度的CsPbBr₃太阳电池的短路电流密度得到有效提高,达7.47 mA/cm²,进而使器件效率提升至7.30%。经测试表征发现,基于1.0 mol/L PbBr₂浓度制备的CsPbBr₃吸收层具有更好的均匀性、更低的粗糙度、更高的光吸收率以及更强的电子和空穴分离能力,从而提升器件效率。

Abstract

In this work, the CsPbBr₃ solar cells based on different concentrations of PbBr₂ are prepared by a multi-step spin coating method. The effect of different PbBr₂ concentrations on the photovoltaic performance of CsPbBr₃ solar cells is studied. The results showed that compared with CsPbBr₃ solar cells based on 0.6, 0.8 and 1.2 mol/L PbBr₂, the short-circuit current density of CsPbBr₃ solar cell with 1.0 mol/L PbBr₂ is effectively improved （7.47 mA/cm²）, which leads to an improvement in device efficiency （7.30%）. Characterization tests revealed that the CsPbBr₃ absorber layer prepared with a PbBr₂ concentration of 1.0 mol/L exhibits better uniformity, lower roughness, higher light absorption, and stronger electron-hole separation capability, leading to improved device efficiency.
