The development of cadmium stannate coatings for utilization in solar energy converters is reviewed. Significant results achieved during the course of the program are as follows: (1) Transparent Cd/sub 2/SnO/sub 4/ films with 1 ohm/square sheet resistance and 85-90% transmission over parts of the visible spectrum can be prepared by RF sputtering; (2) CdSnO/sub 3/ is also a transparent conductor and films with 10-20 ohm/square and 75-85% transmission between 5500-7500 A have been produced by spray coating; (3) The potential of Cd/sub 2/SnO/sub 4/ films for high-temperature greenhouse window coatings and as components in selective absorbers has been evaluated; (4) Backwall Cd/sub 2/SnO/sub 4//CdS/Cu/sub x/S solar cells with about 6% conversion efficiency (AMI sunlight) were fabricated.
