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.

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.
