15-Fold increase in solar thermoelectric generator performance
STEG output power enhancement strategies A STEG generates electrical power when there’s a ΔT across its hot and cold sides. The generated power is expressed as38 $${P}_{{STEG}}={\left({S}_{{TEG}}\varDelta T\right)}^{2}\frac{{R}_{L}}{{\left({R}_{L}+R\right)}^{2}}$$ (1) where \({S}_{{TEG}}\) is the effective Seebeck coefficient of the TEG, R is the total electrical resistance between the TEG terminals, and \({R}_{L}\) is the load resistance. For a given TE material, an effective way to increase
