Alternative fabrication techniques for high-efficiency CuInSe₂ and CuInSe₂-alloy films and cells: Annual subcontract report, 10 November 1987-31 December 1988

This report, the first annual technical progress report for this project, covers the period from November 30, 1987 through December 31, 1988. Results of recent experiments characterizing CuInSe/sub 2/ deposited by reactive magnetron sputtering and by a hybrid sputtering and evaporation technique are presented. Both techniques produce films with chemical and structural properties comparable with those commonly accepted for polycrystalline CuInSe/sub 2/ used in solar cells. Transmission electron microscopic analysis of the films produced by the reactive sputtering and hybrid techniques were found to be generally similar to those fabricated by three-source evaporation in terms of microstructure, composition, lattice-defect structure, and compositional uniformity. 28 refs., 19 figs., 1 tab.
