Classification: CPC H  Y | IPC H

Claim 0:
1. A thermo-photovoltaic cell capable of converting into electric power the radiant power emitted by an incandescent source and of returning to the incandescent source a large amount of the unused radiation, the thermo-photovoltaic cell comprising:
a semiconductor plate having a front face and a back face, the semiconductor plate comprising at least one pn junction or one np junction or one heterojunction,
a plurality of front contact-finger strips placed on the front face, the front contact-finger strips being electrically conductive and making electrical contact with the front face of the semiconductor plate,
a plurality of electrically conductive front busbar-base strips placed on the front face and a plurality of electrically conductive wires, each electrically conductive wire being placed on a corresponding front busbar-base strip and electrically contacting with it, the front busbar-base strips and the electrically conductive wires intersecting the front contact-finger strips, wherein the plurality of front contact-finger strips makes electrical contact with the front busbar-base strips,
a plurality of front pro-reflection strips, each front pro-reflection strip comprising at least one dielectric layer and being arranged between the front face and a front busbar-base strip, the front pro-reflection strips electrically insulating the front busbar-base strips from the semiconductor plate, and
an electrically conductive layer, arranged at the back face, wherein the electrically conductive layer and the back face make electrical contact only at localized electrically conductive strips, either directly or through an intermediate electrically conductive material.
