University of Toledo (Toledo, OH) with Calyxo USA, Inc: Improved Atmospheric Vapor Pressure Deposition to Produce Thin CdTe Absorber Layers. Record cadmium telluride (CdTe) thin film devices utilize an 8-micrometer (µm) thick CdTe layer but duplication of this structure in commercial manufacturing increases material costs and deposition time. This project will reduce the CdTe layer thickness to approximately 1-µm while targeting a 10% module efficiency. Improvements to contacts, uniformity, and monolithic integration will also be achieved. DOE will provide up to $1,164,174 for this approximately $1.7 million project.

University of Toledo (Toledo, OH) with Xunlight: High-Rate Fabrication of a-Si-Based Thin-Film Solar Cells Using Large-area VHF PECVD. Reducing processing costs of amorphous silicon modules has proven difficult because increasing process throughput of conventional deposition processes results in lower device efficiency. This project aims to retain high efficiencies while fabricating high efficiency amorphous silicon and nanocrystalline silicon solar cells at high rates. The project will target 10% conversion efficiency for amorphous silicon/nano crystalline silicon (a-Si/nc-Si) solar cells. DOE will provide up to $1,442,266 for this approximately $1.9 million project.

The U.S. Department of Energy (DOE) today announced that DOE will invest up to $13.7 million, over three years (Fiscal Years 2008 – 2010), for 11 university-led projects that will focus on developing advanced solar photovoltaic (PV) technology manufacturing processes and products. These projects are integral to President Bush’s Solar America Initiative, which aims to make solar energy cost-competitive with conventional forms of electricity by 2015.

Universities selected for these projects will leverage fundamental understanding of materials and PV devices to help industry partners advance manufacturing processes and products. These projects have the potential to significantly reduce the cost of electricity produced by PV from current levels of $0.18-$0.23 per Kilowatt hour (kWh) to $0.05 - $0.10 per kWh by 2015 – a price that is competitive in markets nationwide. Each university will work closely with an industry partner to ensure the projects retain a commercialization focus and that results are quickly transitioned into market ready-products and manufacturing processes. Additionally, students will be exposed to diverse PV-related commercialization efforts, enhancing workforce development in an effort to increase competitiveness and retain qualified scientists in the growing domestic PV research and development industry.

Projects were selected in response to DOE’s June 20, 2007, Funding Opportunity Announcement – University Photovoltaic Process and Product Development Support - which seeks to strengthen university involvement in the rapidly growing PV industry. Negotiations between selected applicants and DOE will begin immediately to determine final project plans and funding levels. Funding is subject to appropriations from Congress.
