A glass substrate may be processed at high temperatures without substantially losing its thermal-strengthening characteristics or deforming. In some examples, the glass substrate exhibits an increased annealing point and/or softening point as compared to standard glass substrates. In some examples, the glass substrate includes a relatively high amount of CaO and/or MgO, and/or a relatively low amount of Na2O, as compared to traditional soda-lime-silica-based glass. Depending on the composition, the glass substrate may be useful, for example, to fabricate a glass-based solar cell that mates two substantially flat glass substrates together.
