METODO DE FABRICACION DE HETEROUNIONES DE SULFURO DE CADMIO SULFURO DE COBRE, QUE EXHIBEN EFECTO FOTOVOLTAICO EN CELULAS SOLARES

摘要

The process consists of (a) immersing a metal substrate in a soln. of suitable pH contg. a Cd salt and colloidal sulphur arising from disproportioning of Na2S2O3; (b) immersing the substrate and film coating in a soln. contg. a Cd salt, complexing agents and cpds. contg. sulphur; (c) withdrawing the substrate with the polycrystalline CdS film; (d) in a soln. contg. a Cu salt, complexing agents and cpd. contg. sulphur; and.
