説明

<jats:title>Abstract</jats:title><jats:p>Bismuth‐based hybrid perovskites are candidates for lead‐free and air‐stable photovoltaics, but poor surface morphologies and a high band‐gap energy have previously limited these hybrid perovskites. A new materials processing strategy to produce enhanced bismuth‐based thin‐film photovoltaic absorbers by incorporation of monovalent silver cations into iodobismuthates is presented. Solution‐processed AgBi<jats:sub>2</jats:sub>I<jats:sub>7</jats:sub> thin films are prepared by spin‐coating silver and bismuth precursors dissolved in n‐butylamine and annealing under an N<jats:sub>2</jats:sub> atmosphere. X‐ray diffraction analysis reveals the pure cubic structure (<jats:italic>Fd</jats:italic>3<jats:italic>m</jats:italic>) with lattice parameters of <jats:italic>a</jats:italic>=<jats:italic>b</jats:italic>=<jats:italic>c</jats:italic>=12.223 Å. The resultant AgBi<jats:sub>2</jats:sub>I<jats:sub>7</jats:sub> thin films exhibit dense and pinhole‐free surface morphologies with grains ranging in size from 200–800 nm and a low band gap of 1.87 eV suitable for photovoltaic applications. Initial studies produce solar power conversion efficiencies of 1.22 % and excellent stability over at least 10 days under ambient conditions.</jats:p>
