Method for producing a light absorbing film with a perovskite-like structure

The invention relates to methods for producing a light-absorbing material with a perovskite-like structure, and can be used to form a light-absorbing layer in the production of photovoltaic cells for saving the materials and increasing the allowable size of converters. These advantages are achieved by forming a uniform layer of component В on the substrate, preparing a mixture of reagents that react with component В under predetermined conditions, and a reaction inhibitor that suppresses this reaction under these conditions; the prepared mixture is applied in stoichiometric amount or greater than stoichiometric on the layer of component В and the reaction inhibitor is removed from the mixture, ensuring activation of the chemical reaction between the mixture of reagents and component В to form films of perovskite-like material.
