20080280058 | Method of Preparing Zinc Oxide Nanorods on a Substrate By Chemical Spray Pyrolysis - A method of preparing nanostructured zinc oxide layers on a substrate by chemical spray pyrolysis at moderate deposition temperatures from 350° C. to 600° C. is disclosed. An aqueous or aqueous alcoholic solution comprising zinc chloride or zinc acetate as precursors is prepared and sprayed onto the preheated substrate so that the precursor reacts to form zinc oxide layer on the substrate. Thiourea or urea may be also added to the solution. Glass, silicon, or metal oxide covered glass can be used as the substrate. | 11-13-2008 |
20100186805 | PHOTOVOLTAIC CELL BASED ON ZINC OXIDE NANORODS AND METHOD FOR MAKING THE SAME - 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. | 07-29-2010 |
20130236646 | METHOD OF PREPARING ZINC OXIDE NANORODS ON A SUBSTRATE BY CHEMICAL SPRAY PYROLYSIS - A method of preparing nanostructured zinc oxide layers on a substrate by chemical spray pyrolysis at moderate deposition temperatures from 350.degree. C. to 600.degree. C. is disclosed. An aqueous or aqueous alcoholic solution comprising zinc chloride or zinc acetate as precursors is prepared and sprayed onto the preheated substrate so that the precursor reacts to form zinc oxide layer on the substrate. Thiourea or urea may be also added to the solution. Glass, silicon, or metal oxide covered glass can be used as the substrate. | 09-12-2013 |
