Abstract:
A process for producing photovoltaic modules, comprising the steps of:positioning a front contact on a substrate;depositing at least one amorphous silicon-containing thin film semiconductor on said front contact;depositing a transparent conductive layer of a dual layer back contact on said amorphous silicon-containing thin film semiconductor;simultaneously laser scribing said transparent conductive layer of said dual layer back contact and said amorphous silicon-containing thin film semiconductor to form a trench through said transparent conductive layer of said dual layer contact and said amorphous silicon-containing thin film semiconductor; and immediately thereafter;depositing a layer of metal on said transparent conductive layer of said dual layer back contact and simultaneously filling said trench with said metal to form an interconnect extending between and connecting said front contact and said dual layer back contact.
