|Title:||Three-Dimensionally Structured CdTe Thin Film Photovoltaic Devices with Self-Aligned Back Contacts: Electrodeposition on Interdigitated Electrodes.|
|Published:||June 25, 2009|
|Abstract:||Cadmium-telluride photovoltaic cells were deposited on substrates patterned with two interdigitated electrodes. Deposition involved application of different potentials to the two electrodes in order to obtain a 3-d gradient of film properties within the films and thus create a photo-active, homojunction device. A co-deposition process yielded near-stoichiometric CdTe over a wide range of potentials. The as-deposited structures have no electrodes on the top surface, which is corrugated as a result of the growth process. Device properties were studied in the as-deposited state. Systematic variation of the geometry of these pre-patterned arrays should improve device performance and enable quantitative measurement and modeling of the performance of these and analogous ,third-generationŠ nanoscale photovoltaic devices.|
