Abstract:

A number of GaAs Solar Cells for high sunlight intensity operation were fabricated and experimentally evaluated. I-V characteristics were determined for 1, 5, and 9 solar constants. Temperature coefficients of OCV, SCC, and Pmax were determined for one sun GaAs cells by measuring cell electrical performance at 50 C steps from - 190 C to 250 C. Results of 1 Mev electron irradiation to 1 x 10 to the 16th power, Mev equivalent electronssq.cm. and welded interconnect investigations are presented. Author
