NOVELTY - The conductive transparent glass substrate comprises a glass sheet (1), a first barrier layer (3) based on oxide, nitride or oxynitride, a conductive functional layer (4) based on doped zinc oxide or doped indium oxide, a protection layer (5) based on silicon nitride, oxynitride or oxycarbide, a second barrier layer based on silicon nitride inserted between the glass sheet and the first barrier layer, and a blocking layer based on nitride inserted between the first barrier layer and the conductive functional layer. The first barrier layer has a thickness of 10-100 nm.    USE - The conductive transparent glass substrate is useful as a front-face electrode for a cadmium telluride photovoltaic cell (all claimed) and as windows in automobiles and doors in oven.    ADVANTAGE - The conductive transparent glass substrate exhibits excellent durability, high resistance to corrosion and high flexibility, and enhances operational efficiency and lifespan of the photovoltaic cell.    DETAILED DESCRIPTION - The conductive transparent glass substrate comprises a glass sheet (1), a first barrier layer (3) based on oxide, nitride or oxynitride, a conductive functional layer (4) based on doped zinc oxide or doped indium oxide, a protection layer (5) based on silicon nitride, oxynitride or oxycarbide, a second barrier layer based on silicon nitride inserted between the glass sheet and the first barrier layer, and a blocking layer based on nitride inserted between the first barrier layer and the conductive functional layer.
