Abstract
Textured superstrates for photovoltaic cells, for example, silicon tandem photovoltaic cells with light scattering properties which are sufficient for light trapping independent of wavelength are described herein. Features of a textured surface of a superstrate, via the method(s) used to make the textured superstrate, can be tailored to provide the desired light scattering/trapping properties. The method includes grinding and lapping or grinding, lapping, and etching of a glass superstrate.
