on the cold side . The authors also used in-situ Raman spectroscopy to test the species distribution of the

system. They found that high concentration difference distribution can indeed be achieved and can exist
stably, achieving the effect of stable and efficient operation of the thermoelectric battery under light. In
addition to theoretical feasibility, the system exhibited a thermopower of 8.2 mV·K in actual application
