Research on High Efficiency, Large-Area CuInSe2-Based Thin-Film Modules, Annual Subcontract Report, 1 May 1991 - 30 April 1992
Objective was to demonstrate 12.5% aperture efficient, large area (3900 cm[sup 2]) encapsulated thin thin CuInSe[sub 2] (CIS) modules. The module design consists of 53 series-connected ZnO/CdS/CIS/Mo/glass cells fabricated on a glass substrate. A baseline characterization of the CIS modules was established during Phase 1. Maps of open circuit voltage provide information on junction quality uniformity. Maps of cell voltages at fixed forward bias show variations in resistance losses due to interconnects. Individual cell I-V curves can be evaluated. Physical nature of defects is correlated using OBIC, EBIC, SEM, tape adhesion, etc. A new world record of 37.7 W and 9.7% aperture efficiency was attained for an encapsulated module; an unencapsulated CIS module plate achieved 40.8 W and 10.5% aperture efficiency.
