Transfer Of GaAs-based Solar Cells Onto Molybdenum And Silicon Substrates

An effective way to reduce III-V cell cost is to reuse the original substrate of a cell by epitaxial lift-off (ELO) technique. Among ELO methods, a famous and successful one is a process involving flexible plastic carrier and external mechanical force. In this study, we present another kind of ELO approach that can transfer GaAs-based cells onto rigid and highly thermal conductive carriers such as molybdenum (Mo) and Si without the use of external mechanical force.
