WebThe solar cell structures are shown in Table 1. Before growth of the structures, epi-ready Si-doped GaAs (100) substrates were pre-degassed in a load lock chamber at 130°C for 1 h. Then the substrates were transferred into the growth chamber and heated up to 600°C under As 4 ambient conditions to remove the oxide layer.In situ 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 ...
