NOVELTY - The substrate (1) has an indium oxide based amorphous electrically conductive transparent film i.e. underlying film (21), and a zinc oxide based crystalline transparent electrically conductive film (22) that are sequentially placed on the substrate to form an uneven surface structure of a surface electrode (2). Thickness of the amorphous conductive film is 200-500nm. Thickness of the crystalline conductive film is 600-2000nm. A backside electrode (4) is formed by an n-type semiconductor layer.    USE - Transparent electrically conductive light-transmitting glass substrate for manufacturing a thin-film solar cell (claimed). Uses include but are not limited to a soda lime silicate glass substrate, a borate glass substrate, a low alkali content glass substrate, and a quartz glass substrate.    ADVANTAGE - The surface electrode is formed by the indium oxide based amorphous transparent electrically conductive film and the zinc oxide based crystalline electrically conductive film, for presenting an optimum uneven surface structure without using an etching process, where the formed surface electrode with higher light confinement effect manufactures a thin film solar cell with higher photovoltaic conversion efficiency. The surface electrode can vary a crystal grain size of a zinc oxide film by changing degree of amorphousness of an indium oxide film so as to obtain a high haze ratio over a broad wavelength range.    DETAILED DESCRIPTION - The amorphous electrically conductive transparent film is composed of indium oxide doped with titanium, tin and gallium. The crystalline transparent electrically conductive film is formed of zinc oxide doped with aluminum, gallium, boron, indium, ferric, silicon, germanium, titanium, zirconium and hafnium. INDEPENDENT CLAIMS are also included for the following:    (1) a method for manufacturing a transparent electrically conductive substrate    (2) a thin-film solar cell comprising a surface electrode    (3) a method for manufacturing a thin-film solar cell.
