Figure 3
Temperature-dependent light-induced degradation of Ga-doped Cz-Si POLO BJ solar cells at 1 sun light intensity and temperatures ranging from 80 to 160 °C. Shown are the relative changes in the measured cell parameters (a) energy conversion efficiency η, (b) open-circuit voltage VOC, (c) fill factor FF, and (d) short-circuit current density JSC versus the illumination time t.
