Abstract
A device, system, and method for a multi junction solar cell are described herein. An exemplary multi-solar cell structure can have a substrate having a first surface having a (111) crystalline etched surface. A dielectric layer can be deposited on the first surface of the substrate. A graded buffer layer can be grown on a second surface of the substrate with the second surface having a (100) crystalline surface. A first solar subcell within or on top of the graded buffer layer and a second solar subcell grown on top of the first solar subcell.
