Abstract
A FPC stack/GaAlAs solar cell system has been optimized using a Monte-Carlo computer model. The calculations show that the overall electrical efficiency can be increased and the thermal relaxation losses in the solar cells can be reduced significantly by matching each solar cell bandgap and dye emission spectrum individually. 7% overall electricall efficiency at an optical power concentration of 2.7 has been calculated in the best case for a three sheet stack, each sheet with a 400.400.2 cbmm geometry.
