Electrical and optical properties of nickel-oxide films for efficient perovskite solar cells

Efficient hole transport layer (HTL) is crucial for realizing efficient perovskite solar cells (PSCs). In this study, nickel-oxide (NiOX) thin-films are investigated as a potential HTL for PSCs. The NiO(X)films are prepared by electron-beam physical vapor deposition at low temperatures. The crystall...
