Schematic of the device for all-day low-grade environmental thermal energy harvesting. (a) Tandem structure of the thermogalvanic cell. (b) Schematic mechanisms of two working models of the thermogalvanic cell and corresponding energy flux. Model 1 (upper) and model 2 (lower) work at daytime and nighttime, respectively.
