Abstract

Metal-halide perovskite solar cells are gaining tremendous attention due to their remarkable efficiencies and applications to niche flexible markets. In this work, we report n-i-p configuration of perovskite solar cell (light irradiated from n-side) fabricated on opaque stainless-steel substrate. The promising acetamidinium-substituted methyl ammonium lead halide is used as an absorber. Thermally deposited semi-transparent Ag (≈ 15 nm) is used as a top-illumination contact. The best device exhibited a power conversion efficiency ≈ 5%; having a short-circuit current density (Jsc) of -10.73 mA/cm2, open circuit-voltage (Voc) of 1V, and fill-factor (FF) of 47%. The poor-performance of the device is mainly attributed to low-transmission from thin Ag top-contact. The efforts are in progress to achieve better performing devices. © 2022 IEEE.
