摘要
Colloidal quantum dot solar cells(CQDSCs) have significantly progressed their power conversion efficiencies(PCEs) as a result of recent developments in their device architecture and interfacial layers.Generally, Surface passivation of Pb S colloidal quantum dots(CQDs) or appropriate interlayers between CQDs and electron transporting layers(ETLs) has been used in highly efficient solar cells.~(1,2) Moreover, electronic extraction conventionally need to pass through the ETLs to the transparent electrode; thus, the properties of the ETLs identically influence the device performance.Hence, We employed polyethylenimine(PEI) doped sol-gel-processed zinc oxide composites(ZnO:PEI) as efficient ETL to improve the PCE of CQDSCs.The promotion of device performance is attribution of defect reduction of ZnO and energy band optimization.
