Abstract :
Solar-cell efficiencies have exceeded 40% in recent years by use of multiple materials that span the solar spectrum, growth of these materials with near-perfect quality, and use of concentration. Growth of near-perfect semiconductor materials is possible when the lattice constants of the materials are matched or nearly matched to that of a single-crystal substrate.
