Abstract
A solar energy collector includes a prism coupled waveguide and a cladding material layer coextensive with the waveguide core. Photovoltaics (PVs) are disposed within the cladding layer, with the PVs active in at least two wavelength ranges. The PVs are further spaced apart depending upon their active wavelength range. The cladding layer may include two or more material layers of at least two different dielectric constants. In that arrangement, the PVs are further grouped such that the PVs disposed in a first one of the cladding layers has a different active wavelength range than an active wavelength range of the PVs disposed in a second cladding layer.
