Spire Semiconductor proposes a novel MOCVD growth scheme that will substantially reduce the production costs of inverted multi-junction solar cells. Incorporating quantum well structures will be investigated as a means to improve device efficiency and end of life cell performance in the space environment. The theoretical target efficiency is 39.8% under the AM0 spectrum.
