摘要： A front transparent conductor assembly and, in one embodiment, a photovoltaic cell, includes at least three transparent conductor layers. In one embodiment, first and second transparent conductors comprised of SnO2 are positioned above and below a third transparent conductor comprised of ZnO2. In one embodiment, the second transparent conductor layer is significantly thicker than either the first or third transparent conductor layers. In one embodiment of a photovoltaic cell incorporating such an assembly, a sealing layer of SiO2 is interposed between a superstrate and the first transparent conductor. In another embodiment, first and second intermediate layers of ZnSnO3 are incorporated into the assembly, with the first intermediate layer interposed between the first and second transparent conductors and with the second intermediate layer interposed between the second and third transparent conductors.

摘要： A substrate carrier is used in an in-line fabrication such as Plasma Enhanced Chemical Vapor Deposition (PECVD) for application of thin film on substrates. The carrier is in thermal communication with the substrate and thereby provides heat sinking. The carrier further permits movement of the substrate past a deposition apparatus at a deposition station.

摘要： A method and apparatus for reducing as-deposited and metastable defects relative to amorphous silicon (a-Si) thin films, its alloys and devices fabricated therefrom that include heating an earth shield positioned around a cathode in a parallel plate plasma chemical vapor deposition chamber to control a temperature of a showerhead in the deposition chamber in the range of 350° C. to 600° C. An anode in the deposition chamber is cooled to maintain a temperature in the range of 50° C. to 450° C. at the substrate that is positioned at the anode. In the apparatus, a heater is embedded within the earth shield and a cooling system is embedded within the anode.
