Abstract
The p-type inorganic semiconductor CuGaO<sub>2</sub> 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 18.51% with long-term stability is achieved. This indicates that CuGaO<sub>2</sub> is a promising HTL for efficient and stable PSCs.
