ABSTRACT:
A photovoltaic device has a body which includes a thin film active region and a layer substantially transparent to solar radiation. The thickness of the transparent layer is such that a first antireflection condition is present for solar radiation at a wavelength which is relatively highly absorbed by the material of the active region. Furthermore, the combined thickness of the transparent layer and active region are such that a second antireflection condition is present for solar radiation at a wavelength which is poorly absorbed by the material of the active region. As a result of the prevailing antireflection conditions the solar radiation absorption efficiency of the photovoltaic device is increased.
