A sub-cell with bandgap of around 1 eV is required to improve the efficiency of multi-junction solar cells beyond what is possible with legacy triple-junction architectures [1]. Solar Junction Corporation has been focused since 2007 on the developmen

Growth of GaN epilayers on silicon (111) is achieved by using a rare earth oxide buffer layer technology. The use of the REO material system allows strain engineering of the silicon wafers prior to GaN growth in order to mitigate stresses formed duri
