Cleavage of lateral epitaxial films for transfer (CLEFT)

What is Cleavage of lateral epitaxial films for transfer (CLEFT)?

A method of producing cheap GaAs solar cells by means of growing a thin-film layer of gallium arsenide on top of a thick, monocrystalline substrate, cleaving the film from the substrate and incorporating it into the PV cell. The technique allows reusing the substrate for growing more gallium arsenide thin films.
