Glass Textures for Photovoltaic Modules - an Overview

Glass textures can fulfil various effects in photovoltaic (PV) modules: enhanced in-coupling for large incidence angles, glare reduction or color appearance with high angular tolerance. These effects are of particular interest for integrated PV (e.g. building or vehicle integration). This overview will describe the texture dependent effects, give design guidelines, describe industrial texturing technologies and show exemplary results.
