Abstract: 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 B on the substrate, preparing a mixture of reagents that react with component B 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 B and the reaction inhibitor is removed from the mixture, ensuring activation of the chemical reaction between the mixture of reagents and component B to form films of perovskite-like material.

Abstract: Organic-inorganic light-absorbing materials with perovskite structure, being used in perovskite solar cells production. The objective of the invention is to provide the possibility of obtaining perovskite using precursors that are in a liquid state without the use of additional substances and reagents.

Abstract: The invention relates to a method for synthesis of films made of light-absorbing material with perovskite-like structure which can be used for fabrication of perovskite solar cells. The method for synthesis of films made of light-absorbing material with perovskite-like structure with a structural formula ACB3 is characterized by sequential deposition of a layer of a reagent C onto a layer of a reagent AB with a thickness determined by stoichiometry of the reaction followed by the immersion of the layers in a liquid or gaseous medium containing reagent B2 where component A states for CH3NH3+, (NH2)2CH+, C(NH2)3+, Cs+ or a mixture thereof, component B states for Cl?, Br?, I? or a mixture thereof, component C states for metals Sn, Pb, Bi, or their melts, oxides, salts.
