A power generating optical filter is described including a transparent substrate; a first substantially transparent electrode disposed atop at least a portion of the substrate; a body of photovoltaic material adapted to generate electron hole pairs in response to the absorption of incident radiation. The body is disposed atop at least a portion of the first electrode; and a second substantially transparent electrode is disposed atop at least a portion of the body of photovoltaic material. The first and second electrodes and the body of photovoltaic material are each fabricated to preselected thicknesses and from materials characterized by preselected indices of refraction for cooperatively establishing optical interference effects, whereby the filter transmits at least a portion of selected wavelengths of radiation incident thereupon substantially differing from wavelengths transmitted by that body of photovoltaic material alone; and optical tuning layer means for modifying the optical transmission of the filter.
