A power generating apparatus according to an aspect of the invention includes a plurality of pn stacks 11, each formed by stacking a p-type semiconductor layer 11a and an n-type semiconductor layer 11b one on top of the other, and a mode switching unit 16 which effects switching to a photovoltaic power generation mode or a thermal power generation mode by connecting the plurality of pn stacks with each other. The mode switching unit 16 effects switching to the photovoltaic power generation mode by connecting the p-type semiconductor layers 11a in parallel with each other and the n-type semiconductor layers 11b in parallel with each other between the plurality of pn stacks 11. The mode switching unit 16 effects switching to the thermal power generation mode by connecting the p-type semiconductor layer 11a and the n-type semiconductor layer 11b in series between different ones of the pn stacks 11. |
