Abstract
The temperature dependence of the I-V parameters of different III-V multi-junction concentrator cells at several concentration levels was investigated. Moreover, the influence of spectral changes on the temperature coefficients of multi-junction solar cells was examined. Complete sets of temperature coefficients of a metamorphic Ga 0.35In 0.65P/Ga 0.83In 0.17As dual-junction cell, a metamorphic Ga 0.35In 0.65P/Ga 0.83In 0.17As/Ge triple-junction cell and a lattice-matched Ga 0.50In 0.50P/Ga 0.99In 0.01As/Ge triple-junction cell determined under well-controlled laboratory conditions are reported.
