We are investigating semiconductor-sensitized thermal cells (STCs) to harness waste heat. STCs convert thermal energy into electricity by utilizing semiconductor thermally excited carriers to drive redox reactions in an electrolyte. Although power generation has been demonstrated with polyethylene glycol (PEG) 1540 solid electrolyte, the ion diffusion mechanism crucial for electricity generation remains unclear. To address this, we examined power generation behavior with different electrolytes at the semiconductor and counter electrodes, aiming to elucidate the detailed power generation mechanism.
