A photovoltaic device comprises: a first cladding material; a photosensitive material having an index of refraction larger than the first cladding material index of refraction, the photosensitive material disposed adjacent the first cladding material; and a second cladding material having an index of refraction smaller than the photosensitive material index of refraction, the photosensitive material disposed between the first cladding material and the second cladding material so as to form a waveguide for confining propagating photons; and first and second electrodes in electrical contact with the photosensitive material.
