  • Publication number: 20110192450
    Abstract: A method of producing nanoparticles of solar light absorbing compound materials based on pulsed laser ablation is disclosed. The method uses irradiation of a target material of solar light absorbing compound material with a pulsed laser beam having a pulse duration of from 10 femtoseconds to 500 picoseconds to ablate the target thereby producing nanoparticles of the target. The nanoparticles are collected and a solution of the nanoparticles is applied to a substrate to produce a thin film solar cell. The method preserves the composition and structural crystalline phase of the starting target. The method is a much lower cost fabrication method for thin film solar cells.

  • Patent number: 7989729
    Abstract: An apparatus for both detecting and repairing a shunt defect in a solar cell substrate. A shunt detection module detects the shunt defect in the substrate, using at least one of lock-in thermography and current-voltage testing. A process diagnostic module determines whether the substrate should be passed without further processing by the apparatus, rejected without further processing by the apparatus, or repaired by the apparatus. A shunt repair module electrically isolates the shunt defect in the substrate. In this manner, a single apparatus can quickly check for shunts and make a determination as to whether the substrate is worth repairing. If it is worth repairing, then the apparatus can make the repairs to the substrate.

  • Publication number: 20110180127
    Abstract: Fabricating a solar cell stack includes forming a nanopatterned polymeric layer on a first surface of a silicon wafer and etching the first surface of the silicon wafer to transfer a pattern of the nanopatterned polymeric layer to the first surface of the silicon wafer. A layer of reflective electrode material is formed on a second surface of the silicon wafer. The nanopatterned first surface of the silicon wafer undergoes a buffered oxide etching. After the buffered oxide etching, the nanopatterned first surface of the silicon wafer is treated to decrease a contact angle of water on the nanopatterned first surface. Electron donor material is deposited on the nanopatterned first surface of the silicon wafer to form an electron donor layer, and a transparent electrode material is deposited on the electron donor layer to form a transparent electrode layer on the electron donor layer.
