This patent describes a photoresponsive device, which device include a substrate, a light scattering back reflector atop the substrate, and a multilayered body of semiconductor material atop the back reflector. This patent describes improvement in the back reflector comprising a tri-layered body including a hard, textured, non-highly reflective layer formed of a material other than copper, aluminum or silver and disposed directly upon the substrate. a highly reflective layer conformally disposed atop the textured layer; and a transparent oxide layer deposited upon the highly reflective layer.
