โœฆ Synopsis

This paper describes work investigating high rate cadmium telluride (CdTe) film deposition by close-space vapor transport, leading to 4 cm 2 tin oxide/CdTe solar cells of efficiency greater than 10%. Under a 100 mW cm -2 air mass 1.5 global spectrum, a cell of efficiency 10.5% had a short-circuit current of 28.1 mAcm -2, an open circuit voltage of 0.663 V and a fill factor of 0.563. Our major achievements include (1) the use of completely nonvacuum processing, (2) the fabrication of simple transparent conductive oxide/CdTe cells without need of a CdS window layer, and (3) screenprinted back contacts.

Studies indicate that 15% module efficiencies are required for central station utility plants. Efficiencies of 9% have been achieved in 30 cm X 30 cm thin film modules with both copper indium diselenide and thin film silicon:hydrogen or "amorphous silicon"; however, it is unlikely that either will r
