Abstract

In this paper, the aluminum induced texturing (AIT) method for glass sheets is applied to two types of glass used in the thin-film PV industry for superstrate modules: soda-lime glass and borosilicate glass. Upon texturing one surface of the glass sheet with the AIT method, an aluminum-doped ZnO (AZO) film is deposited onto the textured glass surface using magnetron sputtering. The properties of the textured glass sheets are investigated using scanning electron microscopy. Then the optical and electrical properties of the AZO-coated AIT glass sheets are analyzed.
