| Summary |
United Solar Ovonic LLC successfully used its spectrum-splitting a-Si:H/a-SiGe:H/a-SiGe:H triple-junction structure in their manufacturing plants, achieving manufacturing capacity of 118 MW in 2007 from its Auburn Hills and Greenville, Michigan plants. United Solar has a very aggressive expansion plan to achieve grid parity by improving its solar panel efficiency, improving manufacturing throughput, and reducing manufacturing cost. In the Thin Film Partnership Program, Uni-Solar identified three areas of research: i) Optimize a-Si:H and a-SiGe:H deposition parameters under the current manufacturing constraints for improving solar module efficiency and manufacturing throughput, and reducing the manufacturing cost; ii) Explore new deposition methods for a-Si:H and a-SiGe:H materials to improve a-Si:H/a-SiGe:H/a-SiGe:H triple-junction cell efficiency at high deposition rates; and iii) Explore new materials and new cell structures for higher efficiency at high deposition rates. |
