聚乙烯亚胺包覆氧化锌电子传输材料的制备及其对有机光伏电池空气和紫外稳定性的增强效应
Refinement of Polyethyleneimine-coated Zinc Oxide Electron Transport Material and Investigation of Its Enhancing Effect on Air and Ultraviolet Stability of Organic Photovoltaic Devices
摘要
Abstract
The interfacial layer materials situated between the active layer and electrodes are critical aspect of or-ganic solar cells(OSCs),as they directly affect device performance and stability during operation.Zinc oxide(ZnO)nanoparticles(NPs)are commonly functioned as electron transport layer(ETL)materials.However,their high surface defect states and susceptibility to adsorbing water and oxygen can significantly impact the efficiency and stability of OSCs.To tackle this issue,a synergistic approach was adopted in this study by employing polyethylenei-mine(PEI)-coated ZnO NPs to passivate surface defects and regulate energy levels.The resulting ZnO@PEI NPs was successfully synthesized using a hydrothermal method and served as an ETL in PM6∶BO-4Cl∶PC61BM-based OSCs.The experimental results indicate that the photovoltaic devices prepared using ZnO@PEI NPs as the ETL ex-hibit a slight decrease in the power conversion efficiency(PCE).However,due to the encapsulated PEI effectively passivating the surface defects of ZnO,the ZnO@PEI NPs devices demonstrate enhanced air and ultraviolet stability.In conclusion,this study proposes an effective strategy for developing multifunctional and highly stable ETL,present-ing a new and practical approach to achieving highly stable OSCs.关键词
