CHALCOPYRITE SEMICONDUCTOR BASED PHOTOVOLTAIC SOLAR CELL COMPRISING A METAL SUBSTRATE, COATED METAL SUBSTRATE FOR A PHOTOVOLTAIC SOLAR CELL AND MANUFACTURING METHOD THEREOF

摘要

A chalcopyrite semiconductor based photovoltaic solar cell. This cell comprises a metal substrate. A conductive layer is present between the metal substrate and a chalcopyrite semiconductor. The conductive layer has a crystal structure fitting to the crystal structure of the chalcopyrite semiconductor. Also disclosed is a coated metal substrate, in particular a metal strip for producing the individual metal substrates of a solar cell, as well as a manufacturing method thereof.
