摘要
GaAs solar cells grown on Si wafers have been investigated for many years to find a way to reduce the solar cell cost, by replacing the expensive Ge substrates with a low cost material and less heavy [1,2]. Both space and terrestrial applications are interested in the development of this type of technology [3]. This paper is presenting the most recent results on this subject. The preparation of so called Si:Ge "virtual wafers" was carried out with a new approach for Ge deposition on Si wafers, originally developed for microelectronic. Both single junction and triple junction GaAs solar cells were manufactured and preliminary tested. Solar cells ranging from a size of 8 cm(2) down to 1 mm(2) were manufactured for terrestrial applications in concentrator systems.
