Abstract :
We discuss approaches to approaches to synthesis of high efficiency low cost photovoltaics that employ single crystal GaAs and Si in thin film and wire array formats. A common theme is the use of lift-off processes that enable cell fabrication without consumption of a thick crystalline wafer per cell. Use of single crystal materials enables the achievement of high open circuit voltages relative to polycrystalline materials.
