Abstract
A method for processing a transparent conductive oxide (TCO) layer in accordance with the present invention comprises the steps of: uniformly depositing the TCO layer on a substantially flat surface of a transparent substrate; and etching the exposed surface of the TCO layer thereof to roughen the exposed surface. The so-treated TCO layer is used as a transparent electrode in photovoltaic devices and has a decreased, substantially constant reflectance throughout the visible light range.
