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