Abstract: Embodiments disclosed herein generally relate to a process of texturing a transparent conductive oxide layer deposited over a substrate. The transparent oxide layer is sometimes deposited onto a substrate for later use in a solar cell device. After the transparent conductive oxide layer is deposited, the layer is textured to increase the haze of the layer. An increase in haze permits the layer to increase light trapping and thus improve the efficiency of a solar cell. A wet etch chemistry that utilizes a component that is less polar than water permits the acidic component, such as nitric acid, to dissociate less and thus etch the transparent conductive oxide to the desired texture. A suitable component is an organic component such as acetic acid which has a dielectric constant substantially below the dielectric constant of water.
