The greatest barrier to the success of GaAs cells has been the high cost of a single-crystal GaAs substrate. For this reason, GaAs cells are used primarily in concentrator systems, where the typical concentrator cell is about 0.25 cm 2 in area and can produce ample power under high concentrations. In this configuration, the cost is low enough to make GaAs
