In this work, we present results of all-inorganic Cs-based halide perovskite solar cells on three compositions: CsPbI₃, CsPbBr₃ and CsPbCl₃. The optical and photovoltaic performance was investigated by means of numerical simulations for different halide species. The device has a C₆₀ ETL and an SWCNT HTL structure. The performance of CsPbX3 (X = Cl or I) perovskites was found to strongly depend on the halide composition; among them, CsPbI₃ based device showed a record best efficiency (PCE = 19.9%, Jsc = 24.9 mA/cm², FF = 72%), suggesting its potential for high‐efficiency applications.
