Abstract :
Recent CuInSe2 (CIS) thin-film module development emphasized process control and module durability. CIS submodules, 0.4 m 2 in size with aperture-area efficiencies of 9.7% and power outputs of 37.8 W were fabricated using production-compatible processing techniques. Module stability was measured on 0.1 m2 prototypes at several outdoor test sites. Modules changed less than 6% after 171/2 months of continuous outdoor exposure. Module durability was also evaluated in accelerated life tests based on the Jet Propulsion Laboratory Block-V environmental tests. Median module power changed less than 8% after 10 humidity-freeze cycles, and good mechanical adhesion existed between the CIS layer and the substrate
