In article number 1602556, Licheng Sun and co-workers report an efficient perovskite solar cell (PSC) based on a solution processable nickel(II) phthalocyanine (NiPc) and vanadium oxide (V2O5) integrated hole transport layer. The introduction of the NiPc thin layer on the perovskite surface greatly restricts the crystalline incommensurate effects between perovskite layer and V2O5 layer, and correspondingly facilitates the formation of a thin and uniform V2O5 layer on top of NiPc/perovskite. The integrated HTL shows enhanced hole extraction efficiency and the optimized PSC displays an impressive average PCE of 17.6% under one sun illumination.
