| Abstract: | An organic–inorganic integrated hole transport layer (HTL) composed of the solution‐processable nickel phthalocyanine (NiPc) abbreviated NiPc‐(OBu)8 and vanadium(V) oxide (V2O5) is successfully incorporated into structured mesoporous perovskite solar cells (PSCs). The optimized PSCs show the highest stabilized power conversion efficiency of up to 16.8% and good stability under dark ambient conditions. These results highlight the potential application of organic–inorganic integrated HTLs in PSCs. |
