Abstract :
Results of optical and compositional analyses of films for solar cells produced by thermal annealing of elemental layer structures are presented and compared with data from laser processed structures. The variation of resistivity with composition is shown. Using conventional large-area vacuum deposition techniques, copper, indium, and selenium were evaporated in the form of a sandwich, which was then thermally annealed. Chalcopyrite copper indium diselenide, of both p- and n-type conductivity, was formed with satisfactory optical and electrical properties.
