Abstract or Summary
  • The materials Fe₂(Si,Ge)(S,Se)₄, Cu₃PS[subscript 4-x]Se[subscript x] (0 ≤ x ≤ 4), and Cu₃PxAs[subscript 1-x]S₄ (0 ≤ x ≤ 1) have been synthesized and studied as new earth-abundant absorbers for single and multijunction photovoltaic cells as well as solar fuel generation. The synthesis, single-crystal growth, and optical and electrical properties of these materials are described and discussed in Chapter 2, 3, and 4. Inspired by the photovoltaic absorber Cu₂ZnSnS₄, the new compound CuZnPS₄ has been discovered; its structure and properties are discussed in Chapter 5, including a comparative analysis to Cu₃PS₄. The compound YZrF₇ (Chapter 6) has been synthesized and evaluated for the first time as a new optical host for green up-conversion.
