“…After the 1 st -Run experiment, as reported in work [146], three process adaptations were made in the 2 nd -Run experiment: the p-type Si layer is now microcrystalline rather than amorphous; the realized samples were optionally annealed at 140 °C in N 2 ambient for 16 hours; and the optional Au grid mentioned in [146] has not been employed for the new experiments, at the expense of solar cell efficiency, for a better comparison. In addition, the active area of the realized solar cells in the 2 nd Run is 0.16 cm 2 for all the samples.…”
