A high efficiency A1GaAs/Si tandem solar cell has been fabricated by metal-organic chemical vapor deposition (MOCVD). It consists of a A10.15Gao.s5As top cell and a Si bottom cell. The crystalline quality of the A10asGa0.s5As heteroepitaxial layer grown on Si has been improved using a high temperatu
