TECHNOLOGY FOR PRODUCTION OF METALLIC NANOLAYERS ON SILVER ELECTRIC CONTACTS OF SILICON SOLAR CELLS USING CHEMICAL METHOD

摘要

FIELD: material engineering.; SUBSTANCE: method of application of metallic nanolayers in chemical method involves the technology of chemical sedimentation of metals, in particular of copper (Cu) at the speed 1 μm/min with the solution temperature 50 to 60°C. As the basic copper-containing reagent for applying metallic nanolayers on silver electric contacts of silicon solar cells the inorganic copper salts are used. Technical result of the invention is the thickening of frontal electric contact of solar cell by sedimentation of metals, in particular copper, with good electric conductivity, in order to compensate or improve its increased electric conductivity.; EFFECT: increased effectiveness of solar cell operation during transformation of high-density radiation and decreased self-cost of its manufacturing.;4 cl, 4 dwg
