Description

Unencapsulated thin-film solar cells of the Cu/sub 2/S/CdS type have been aged in controlled flowing-gas ambients to characterize changes in their photovoltaic properties. Severe degradation occurring in wet O/sub 2/ ambients at room temperature probably accounts for the large short-circuit current losses reported earlier. Limited loss (<15% of initial values) in J/sub sc/ occurs at RT in dry oxygen. No loss can be attributed to moisture in Ar or N/sub 2/ ambients for exposure times greater than approx. 2 hrs. Direct measurements of optical absorption in the front Cu/sub 2/S layer would be facilitated by an integral CdS/Cu/sub 2/S detector ... continued below

Direct measurements of optical absorption in the front Cu/sub 2/S layer would be facilitated by an integral CdS/Cu/sub 2/S detector on the back surface. Several techniques for making such a detector were successfully demonstrated.
