Abstract
The benefits of the ultra high concentration (> 1000 suns) are shown in terms of cost reduction and efficiency increase. Consequently, a GaInP/GaAs dual junction cell specifically designed for operation at 1000 suns is developed and manufactured and. Its measurement -carried out at the Calibration Laboratory (CalLab) of Fraunhofer Institute (FhG-ISE) in Freiburgresults in an efficiency of 32.6% for a concentration range going from 499 to 1026 suns. This efficiency is the world record efficiency for a dual junction solar cell. Besides, the efficiency is still as high as 31% at 3000 suns.
