Abstract

A perovskite material CsAg₂Sb₂I₉ was developed by dissolving CsI, AgI and SbI₃ in DMF (molar ratio 1 : 2 : 2). CsAg₂Sb₂I₉ solar cells gave a power conversion efficiency of 0.99% and a fill factor of 67.1%. The morphology of a CsAg₂Sb₂I₉ film was affected significantly by the CsI content in the precursor solution.
