Advances in Heterointegration of III-V/Si Solar Cells

Professor Steven A. Ringel talked about metamorphic epitaxy and lattice engineering for III/V on Si solar cells today morning. In the talk, he presented a special MBE method called migration enhanced epitaxy, which the heterovalent III-V/IV nucleation-related defects are simultaneously eliminated. This technique provides a promising future for for III–V/Si device technologies.
