METHODS OF PREPARING FLEXIBLE PHOTOVOLTAIC DEVICES USING EPITAXIAL LIFTOFF, AND PRESERVING THE INTEGRITY OF GROWTH SUBSTRATES USED IN EPITAXIAL GROWTH

摘要

There is disclosed methods of making photosensitive devices, such as flexible photovoltaic (PV) devices, through the use of epitaxial liftoff. Also described herein are methods of preparing flexible PV devices comprising a structure having a growth substrate, wherein the selective etching of protective layers yields a smooth growth substrate that us suitable for reuse.
