摘要

CsPbIBr perovskite solar cells (PSCs) have garnered significant attention owing to their remarkable thermal stability and desirable bandgap. However, CsPbIBr-based devices still face critical challenges, particularly at the interfaces between the active layer and adjacent components. In this study, a multifunctional ZnO composition has developed as the electron transporting layer (ETL) for CsPbIBr PSCs, enabling simultaneous efficient charge extraction and passivation of buried interface defects in CsPbIBr. The nanocomposite, composed of PbCl-modified ZnO (PbCl-ZnO), facilitates the regulation of bandgap and conduction band to align the energy level of ETL and CsPbIBr. Additionally, the residual PbCl at the buried interface of the perovskite incorporates into the perovskite lattice, reducing I defect and thus improving film quality. The improved energy level alignment at the ETL/CsPbIBr interface and the suppressed I defect-induced carrier nonradiative recombination result in a remarkable reduction in energy loss from 0.73 to 0.52 eV. Finally, the PbCl-ZnO hybrid nanocomposite ETL significantly enhances the efficiency of CsPbIBr PSCs, increasing it from 14.15% to 17.46%, representing one of the highest reported power conversion efficiency (PCE) values for CsPbIBr PSCs. These findings demonstrate the potential of PbCl-ZnO hybrid nanocomposite as an effective ETL for CsPbIBr PSCs.
