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.
