Abstract

A method for producing a perovskite material photovoltaic device, the method comprising: depositing a layer comprising a fullerene or fullerene derivative on a perovskite material; depositing a cross-linking agent on the perovskite material or the layer comprising the fullerene or fullerene derivative, wherein the cross-linking agent comprises a silane, wherein the silane is a halosilyalkane; and depositing one or more polymers on the perovskite material or the layer comprising the fullerene or fullerene derivative.
