Possible implementations of these designs are suggested, based on design constraints such as lattice matching, use of possible substrates, and ease of material growth, and then simulated. In order to realize these implementations, it was required to include Tl-bearing semiconductor materials in the simulations; this is a class of materials that has not been extensively studied, particularly for use in photovoltaics. Incorporation of this class of materials in photovoltaics is shown to both improve the effectiveness of some high performance cells already studied by other groups as well as allow for new high conversion efficiency band structures.; Thesis (M.S.)--Tufts University, 2011.; Submitted to the Dept. of Electrical Engineering.; Advisor: Thomas Vandervelde.; Committee: Jeffrey Hopwood, and Fiorenzo Omenetto.; Keyword: Electrical Engineering. %[ 2022-10-12 %9 Text %~ Tufts Digital Library %W Institution
