The U.S. Department of Energy (DOE) is proposing to provide federal funding to The Ohio State University (OSU) to increase the efficiency of crystalline Si-based tandem solar cells and modules in a systematic research, development, and optimization project.
The proposed project involves the metalorganic chemical vapor deposition (MOCVD) and fabrication of III-V tandem solar cell devices within dedicated University and commercial laboratory facilities. Activities associated with the proposed project would include the design, deposition, fabrication, and characterization of these devices. Design modeling, sample preparation, microscopy, deposition, fabrication, and characterization activities would take place in specialized laboratories at OSU in Columbus, OH. Additional deposition and characterization activities as well as cost analysis work would occur at both the National Renewable Energy Lab (NREL) in Golden, CO and the commercial manufacturing facility of SolAero Technologies in Albuquerque, NM. All aspects of solar cell processing including oxidation, patterning, metallization and annealing would be undertaken in the High Efficiency Photovoltaics Lab at the University of New South Wales (UNSW) in Kensington, Australia.
