  • Patent number: 9065006
    Abstract: A device, method and process of fabricating an interdigitated multicell thermo-photo-voltaic component that is particularly efficient for generating electrical energy from photons in the red and near-infrared spectrum received from a heat source in the near field. Where the absorbing region is germanium, the device is capable of generating electrical energy by absorbing photon energy in the greater than 0.67 electron volt range corresponding to radiation in the infrared and near-infrared spectrum. Use of germanium semiconductor material provides a good match for converting energy from a low temperature heat source. The side that is opposite the photon receiving side of the device includes metal interconnections and dielectric material which provide an excellent back surface reflector for recycling below band photons back to the emitter. Multiple cells may be fabricated and interconnected as a monolithic large scale array for improved performance.
