    摘要: A method for synthesizing Cu(InxGa1-x)S2 and Cu(InxGa1-x)Se2 nanopowders using flame spray pyrolysis to form solar cell absorber materials. The flame spray product is the oxide nanoparticles of the absorber materials (copper indium gallium oxide). The oxide nanoparticles may be deposited directly onto glass substrates. The oxide nanoparticles are then sulfurdized or selenized with a post deposition anneal directly on the substrate to form the absorber layer for a solar cell device.

    摘要: A laser apparatus uses a dysprosium doped chalcogenide glass fiber. The glass fiber has a laser pump operatively connected to it. The chalcogenide glass fiber is located in a laser cavity including one or more reflective elements such as a Bragg grating, a Bragg minor, a grating, and a non-doped fiber end face. The apparatus provides laser light output at a wavelength of about 4.3 μm to about 5.0 μm at a useful power level using laser light input at a wavelength of from about 1.7 μm to about 1.8 μm. Also disclosed is a method for providing laser light output at a wavelength of about 4.3 μm to about 5.0 μm using the apparatus of the invention.
