Claim 0:
1. An optoelectronic device, comprising:
a substrate;
a reflector disposed on the substrate; and
a thermophotovoltaic cell bonded to the reflector and configured to receive thermal radiation incident thereon, wherein the thermophotovoltaic cell is comprised of active device layers and a spacer layer, such that the spacer layer is positioned in between the reflector and the active device layers, and the spacer layer includes a cavity formed between the active device layers and the reflector, and the cavity in the spacer layer is filled with air, wherein the spacer layer and reflector operate to reflect photons having energy less than band gap of materials comprising the thermophotovoltaic cell.
