The p‐type inorganic semiconductor CuGaO2 as a hole‐transporting layer (HTL) in perovskite solar cells (PSCs) provides higher carrier mobility, better‐energy level matching, and superior stability, as well as low‐temperature processing technique. Compared to organic HTL, a very competitive PCE of 18...
