Power conversion efficiency of a 54 μm-thick InGaP/InGaAs/Ge trple-junction solar cell was investigated at −150 °C–+150 °C under AM0 condition.
Temperature-dependent external quantum efficiency of transferred thinned solar cell was investigated.
A structural deformation was observed in the transferred thinned solar cell.
The deformation affected the temperature-dependent photovoltaic properties of the transferred thinned solar cell.
