Abstract
A patterned glass substrate is provided for use in a solar cell. The glass substrate is both patterned on at least one surface thereof and has a low iron content. The combination of low iron content, optional oxidizing agent, and the patterning of the glass substrate results in a substrate with high visible transmission and excellent light refracting characteristics.
