Thermophotovoltaic systems (photovoltaic cells specially adapted for conversion or sensing of infra-red [IR] radiation H01L 31/00; thermoelectric devices H01L 35/00) Definition statement This place covers: Systems formed by an infrared radiation emitting source and by a (an array of) low band-gap solar cell(s) which are specifically sensitive to the infrared spectrum emitted by the source. Generally two types of system are the most common one: one in which a special emitter (of refractory materials) is heated (e.g. by a gas flame) and emits a specially adapted infrared spectrum, the other in which the solar light is concentrated in a cavity and converted by the solar cells situated in the cavity. This subgroup is used to classify documents covering aspects of the systems, including the specific radiators.  Relationships with other classification places Documents featuring photovoltaic cells optimized for IR radiation spectrum are classified and found in the solar cell groups covering the cell structure or the cell materials (H01L 31/06 and subgroups). Cells for TPV described independently from the TPV system are classified in the groups according to materials, structure, etc (H01L 31/068) since they merely refer to solar cells specifically sensitive to IR (IR forming also a part of the solar spectrum) References Limiting references This place does not cover:
