  • Thermophotovoltaic system
    Patent number: 8669464
    Abstract: A thermophotovoltaic system is described. The thermophotovoltaic system includes a chamber body, an emitter, a filter and a photovoltaic cell. The chamber body has an ellipsoid chamber including a first focus and a second focus. The emitter is disposed on the first focus, and the emitter is suitable for emitting a plurality of electromagnetic waves. The filter is surrounding the emitter to filter the electromagnetic waves and to pass the electromagnetic waves with a predetermined wavelength band. The photovoltaic cell is disposed on the second focus and is suitable for receiving the electromagnetic waves with the predetermined wavelength band.

  • CELL FOR REDUCING RECOMBINATION OF ELECTRONS AND HOLES AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20130327379
    Abstract: A cell has a substrate, a first microstructure and an active layer. The first microstructure is formed on the substrate and has therein a first material with a concentration gradient toward one side of the substrate to provide a first built-in electric field. The active layer is mounted on the first microstructure so as to reduce recombination of electrons and holes in the cell.
