Abstract
Solar cells based on GaAs are required in order to reach the efficiencies required by space applications. It is shown that subject to certain boundary conditions the efficiency of GaAs/Ge cells can reach 24% when the dual junction configuration is used or approximately 19.5% if the Ge substrate is passive. The electrooptical properties of these cells are reviewed, and prospects for achieving these efficiency goals are examined. Cell construction, cell performance modeling, and experimental performance data are discussed
