METHOD FOR PRODUCTION OF ABSORBING LAYER CuZnSnS FOR SOLAR CELLS Russian patent published in 2009 - IPC H01L31/18

Abstract RU 2347299 C1

FIELD: physics.

SUBSTANCE: method for production of Cu₂ZnSnS₄ layer is realised in two stages, on the first stage of which basic layer of metal components, and/or sulfides is applied onto substrate with conducting contact by methods of vacuum sputtering with atomic ratio of components required for synthesised compound, and at the second stage produced structure is sulfidised. Metal layers are sulfidised in atmosphere created by continuous flow of inertial gas and vapours of sulphur from the source unlimited for the time of reaction, at the temperature of 220-450°C for the time required for synthesis of single phase layer of Cu₂ZnSnS₄ compound.

EFFECT: production of layers Cu₂ZnSnS₄ with specified physical characteristics (crystalline structure, phase composition, surface morphology, width of prohibited zone, etc) by simplification of production technology and increase of process ecological safety.
