In order to form a film of organic-inorganic hybrid material, such as a perovskite material, in a selected stoichiometric ratio upon a surface of a substrate, the proposed method entails a number of simple steps. First, a substrate and a selected quantity of an organic-inorganic hybrid material are placed in a chamber, with the hybrid material being placed on a heater. Then, the hybrid material is heated sufficiently, as by passing an electric current through the heater, to cause its total ablation. As a consequence, a film of the organic-inorganic hybrid material, in the aforesaid selected stoichiometric ratio, reassembles as a film upon a surface of the substrate. During the heating step, the chamber may be either evacuated to a pressure below 10-3 torr or filled with an inert gas, such as nitrogen.
