Copper sulfide films are formed on glass by sputtering a copper target in a H/sub 2/S/Ar atmosphere. The properties of the films are investigated by various electrical and optical measurements, while the sputtering parameters are varied. Films with a suited stoichiometry, crystallography and resistivity for solar cell application are then sputtered onto evaporated CdS films. The influence of some parameters such as the CdS thickness, chemical and sputter etching, the Cu/sub 2/S thickness and post fabrication annealing on the solar cell characteristics is investigated. The best cell obtained is characterized by : J /SUB sc/ = 13.75 mA/cm/sup 2/, V /SUB oc/ = 0.572 Volt, FF = 62,5%, /eta/ = 4.9%. A brief discussion is given on these parameters, on J /SUB sc/ versus V /SUB oc/ measurements , on I-V measurements in the dark and on C-V measurements.
