摘 要：With increasingly improving efficiency of perovskite solar cells(PSCs), top priority has been given to the stability, lifetime, and alternative heavy metal element lead of the ***, on the basis of conventional PSCs, a high-performance device was prepared using a vanadium pentoxide(VO) film to modify the poly(3,4-ethylene dioxy-thiophene)–poly(styrene sulfonate)(PEDOT:PSS) hole transport *** VO modified layer prevents the acidic PEDOT:PSS film from etching the indium tin oxide electrode and maintains the stability of the PSC *** addition, a 4,7-diphenyl-1,10-phenanthroline modified layer prevented the photoactive layer film from coming into direct contact with the Ag electrode to enhance the lifetime of the PSC stored in the *** our study, a stable power conversion efficiency of 15.49% was achieved using this *** to the same type of devices, this type of device exhibited excellent performance and its stability was much higher than that of other device structures when stored in *** modifying the transport layers to enhance the stability and longevity of the PSC, a method is provided for reference for further research.
