Abstract

A multilayered, light-scattering back reflector for a photovoltaic device, said back reflector including a first relatively hard, textured layer atop a substrate and a second highly reflective layer conformally disposed atop the first layer. The back reflector may further include a third light scattering layer formed atop said second layer, said third layer adapted to further provide a barrier layer between the body of semiconductor material from which the photovoltaic device is formed and the multilayered back reflector.
