1. A method of making a photovoltaic device, the method comprising:

  • providing a soda-lime-silica based glass substrate which comprises from about 67-75% SiO2, from about 10-20% Na2O, from about 5-15% CaO, from about 0.1 to 8% MgO, and from about 0.1 to 5% Al2O3;

    etching at least one major surface of the glass substrate to form a textured surface of the glass substrate, wherein an etching ratio ((Al2O3/Na2O)* (MgO/CaO)) of the glass substrate is at least about 0.010, and a ratio MgO/CaO in the glass substrate is at least about 0.45;

    sputter-depositing a substantially transparent and electrically conductive front electrode on the textured surface of the glass substrate; and

    using the front electrode formed on the textured surface of the glass substrate at a light incident side of a photovoltaic device.
