Haacke, G; Burton, L C

Progress made during the reporting period has yielded the following results: (1) Cadmium stannate films with 6500/ohm cm conductivity and high optical transmission can be prepared by sputtering; (2) Clear cadmium stannate films with 10-20 ohm/square sheet resistance can be spray coated. Sheet resistances as low as 5 ohm/square have been achieved; (3) Junction-free, 1 ohm/square cadmium stannate contacts have been sputtered onto single crystal silicon wafers; and (4) Backwall efficiencies of 5.3% under tungsten illumination (about 6% AMI sunlight) were measured in Cd/sub 2/SnO/sub 4//CdS/Cu/sub x/S cells.
