WebMetal organic chemical vapor deposition (MOCVD) is usedto grow high-quality epitaxial GaAs solar cell structure on "single-crystalline-like"germanium film on epi-ready metal tape. These epitaxial GaAs filmsexhibit excellent crystalline alignment with high carrier mobility.The fabricated device is further processed for contact depositionvia ... WebOct 7, 2024 · Since the industry favours efficiency over cost for outer space power generation, multijunction GaAs cells are usually used for concentrator solar structures and spacecraft-based solar energy as they can be operated at an extremely higher temperatures compared to a (c-Si) based solar system [ 12, 13, 14 ].
