Abstract

An improved epitaxial lift-off (ELO) technique is developed and monocrystalline CdTe/MgCdTe double-heterostructure (DH) thin films on conductive flexible superstrates are demonstrated. The post-ELO DH shows strong photoluminescence and uniform surface morphology comparable to that prior to the lift-off process. Solar cells fabricated with the post-ELO thin films exhibit an open circuit voltage of 0.79 V and an efficiency of 9.8%, showing that the ELO technique is practical for fabrication of flexible, light-weight monocrystalline CdTe solar cells for space and terrestrial applications.
