  • Photovoltaic cell based on zinc oxide nanorods and method for making the same
    Patent number: 8614393
    Abstract: A new photovoltaic (PV) cell structure, prepared on transparent substrate with transparent conductive oxide (TCO) layer and having nanorod zinc oxide layer. The cell has a thin conductive layer of doped zinc oxide deposited on the nanorod zinc oxide layer, an extremely thin blocking layer of titanium oxide or indium sulfide on the thin conductive layer, a buffer layer of indium sulfide on the extremely thin blocking layer, an absorber layer, comprising copper indium disulfide on said buffer layer and one electrode attached to the transparent conductive oxide layer and a second electrode attached to the absorber layer. Also, a method of preparing a zinc oxide nanorod PV cell entirely by chemical spray pyrolysis is disclosed. Efficiency up to 3.9% is achieved by simple continuous non-vacuum process.
    Type: Grant
