ABSTRACT:
An optically enhanced back reflector for a photovoltaic device includes a back reflector layer of aluminum having a multi-layered, reflectivity enhancement member deposed thereon. The multi-layer enhancement member includes at least one pair of first and second layers, the first layer having a low index of refraction and the second layer having a high index of refraction. A layer of transmissive conductive oxide is disposed between the optically enhanced back reflector and the photovoltaic device.
