Abstract:Composition of an AlGaAs/GaAs/Ge triple-junction solar cell were analyzed using an equivalent circuit. The current-voltage (I-V) characteristics and impedance spectroscopy(IS) of it were measured in the temperature range from 20  C to 180  C. In the high-temperature range (from 140  C to 200  C) the VOC changes faster than those in the low-temperature range (from 20  C to 80  C).This is because contribution of the VOC from the Ge subcell becomes nearly zero in the high temperature. R and C of the bottom subcell keep almost the same in the high temperature. ? (2013) Trans Tech Publications, Switzerland.
