Abstract

Uniform perovskite films are achieved by HCl-assisted one-step spin-coating at room temperature. By this method, a highest power conversion efficiency of 17.9% is obtained for perovskite solar cells (PSCs). The devices retain ≈95% of their original efficiency after storage in air for two months. The highest efficiency obtained for large-area PSCs (0.86 cm² ) is 15.7%.

Keywords: air-stable; high efficiency; hydrochloride; perovskite solar cells; room temperature.
