摘要
With increasingly improving efficiency of perovskite solar cells(PSCs), ~([1-3]) top priority has been given to the stability, lifetime, and alternative heavy metal element lead of the devices.Herein, on the basis of conventional PSCs, a high-performance device was prepared using a vanadium pentoxide(V_2O_5) film to modify the poly(3,4-ethylene dioxy-thiophene)–poly(styrene sulfonate)(PEDOT:PSS) hole transport layer.The V_2O_5 modified layer prevents the acidic PEDOT:PSS film from etching the indium tin oxide electrode and maintains the stability of the PSC structure.In 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 air.In our study, a stable power conversion efficiency of 15.49% was achieved using this method.Compared 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 air.On modifying the transport layers to enhance the stability and longevity of the PSC, a method is provided for reference for further research.
