摘要： A high efficiency thin-film photovoltaic module is formed on a substrate. The photovoltaic module includes a plurality of stripe shaped photovoltaic cells electrically coupled to each other and physically disposed in parallel to the length one next to another across the width. Each cell includes a barrier material overlying the surface and a first electrode overlying the barrier material. Each cell further includes an absorber formed overlying the first electrode. The absorber includes a copper gallium indium diselenide compound material characterized by an energy band-gap of about 1 eV to 1.1 eV. Each cell additionally includes a buffer material overlying the absorber and a bi-layer zinc oxide material comprising a high resistivity transparent layer overlying the buffer material and a low resistivity transparent layer overlying the high resistivity transparent layer.

摘要： An apparatus for reactive thermal treatment of thin film photovoltaic devices includes a furnace tube including an inner wall extended from a first end to a second end. The apparatus further includes a gas supply device coupled to the second end and configured to fill one or more working gases into the furnace tube. Additionally, the apparatus includes a cover configured to seal the furnace tube at the first end and serve as a heat sink for the one or more working gases. Furthermore, the apparatus includes a fixture mechanically attached to the cover. The fixture is configured to load an array of substrates into the furnace tube as the cover seals the furnace tube. Moreover, the apparatus includes a crescent shaped baffle member disposed seamlessly at a lower portion of the inner wall for blocking a convection current of the one or more working gases cooled by the cover.

摘要： Double well structures in electro-absorption modulators are created in quantum well active regions by embedding deep ultra thin quantum wells. The perturbation introduced by the embedded, deep ultra thin quantum well centered within a conventional quantum well lowers the confined energy state for the wavefunction in the surrounding larger well and typically results in the hole and electron distributions being more confined to the center of the conventional quantum well. The extinction ratio provided by the electro-absorption modulator is typically increased.

摘要： A method for forming a bifacial thin film photovoltaic cell includes providing a glass substrate having a surface region covered by an intermediate layer and forming a thin film photovoltaic cell on the surface region. Additionally, the thin film photovoltaic cell includes an anode overlying the intermediate layer, an absorber over the anode, and a window layer and cathode over the absorber mediated by a buffer layer. The anode comprises an aluminum doped zinc oxide (AZO) layer forming a first interface with the intermediate layer and a second interface with the absorber. The AZO layer is configured to induce Fermi level pinning at the first interface and a strain field from the first interface to the second interface.
