  • Publication number: 20110100413
    Abstract: An apparatus, system, and method are disclosed for restoring efficiency of a photovoltaic cell. An illumination module illuminates photovoltaic cells so the cells receive a time integrated irradiance equivalent to at least 5 hours of solar illumination. After illumination, an annealing module anneals the photovoltaic cells at a temperature above 90 degrees Celsius for a minimum of 10 minutes. In one embodiment, the illumination module illuminates the photovoltaic cells for a time integrated irradiance equivalent to at least 20 hours of solar illumination. In another embodiment, the illumination module illuminates the photovoltaic cells for a time integrated irradiance equivalent to at least 16 hours of solar illumination while being heated to at least 50 degrees Celsius. In another embodiment, a solar concentrator irradiates the photovoltaic cells in sunlight for at least 10 hours and increases the irradiance of solar illumination on the cells by a factor of 2 to 5.

  • Publication number: 20110100420
    Abstract: An apparatus, system, and method are disclosed for a photovoltaic module, the photovoltaic module comprising a plurality of photovoltaic cells, a controllable infrared protection layer, and a protection switching means. The controllable infrared protection layer is for reducing the infrared radiation absorbed by the photovoltaic module, where the controllable infrared protection layer has a first state and a second state. When the infrared protection layer is in the first state the transmission of infrared radiation to the photovoltaic cells is higher than when the infrared protection layer is in the second state. The protection switching means is for switching the controllable infrared protection layer between the first state and the second state.

  • Publication number: 20110100453
    Abstract: A method for manufacturing one or more electrically contactable grids on at least one surface of a semiconductor substrate for use in a solar cell product includes the following. A heat-sensitive masking agent layer is deposited on the surface of the substrate of the solar cell product. The masking agent layer is locally heated to form a grid mask. Selected parts of the masking agent layer defined by locally heating are removed to form openings in the grid mask. A contact metallization is applied on the grid mask.

  • Publication number: 20110100443
    Abstract: A method for manufacturing a photovoltaic solar cell device includes the following. A p-n junction having a first doping density is formed. Formation of the p-n junction is enhanced by introducing a second doping density to form high doped areas for a dual emitter application. The high doped areas are defined by a masking process integrated with the formation of the p-n junction, resulting in a mask pattern of the high doped areas. A metallization of the high doped areas occurs in accordance with the mask pattern of the high doped areas.

  • Publication number: 20110037143
    Abstract: An aluminum lateral interconnect of a Back End of the Line (BEOL) is used to define the x and y dimensions of a through-silicon via in a semiconductor chip formed in a silicon substrate. The TSV includes one or more aluminum annulus formed on a surface of the substrate, and a deep trench in the substrate having a diameter that is determined by the diameter of the aluminum annulus. The annulus can also be provided with a conductive strap upon which a capacitor can be formed. The strap can also be used to provide a connection of the TV to other BEOL interconnects.

  • Publication number: 20100319962
    Abstract: A contiguous deep trench includes a first trench portion having a constant width between a pair of first parallel sidewalls, second and third trench portions each having a greater width than the first trench portion and laterally connected to the first trench portion. A non-conformal deposition process is employed to form a conductive layer that has a tapered geometry within the contiguous deep trench portion such that the conductive layer is not present on bottom surfaces of the contiguous deep trench. A gap fill layer is formed to plug the space in the first trench portion. The conductive layer is patterned into two conductive plates each having a tapered vertical portion within the first trench portion. After removing remaining portions of the gap fill layer, a device is formed that has a small separation distance between the tapered vertical portions of the conductive plates.
