Abstract
A method for forming a photovoltaic device includes forming a photovoltaic absorption stack on a substrate including one or more of I-III-VIand I-II-IV-VIsemiconductor material. A transparent conductive contact layer is deposited on the photovoltaic absorption stack at a temperature less than 200 degrees Celsius. The transparent conductive contact layer has a thickness of about one micron and is formed on a front light-receiving surface. The surface includes pyramidal structures due to an as deposited thickness. The transparent conductive contact layer is wet etched to further roughen the front light-receiving surface to reduce reflectance.
