a Schematic of enhancing STEG output power through hot- and cold-side thermal management. The hot-side thermal management system consists of a W-SSA and a greenhouse chamber to reduce heat loss. The cold-side thermal management system consists of a μ-dissipator, which enhances the cold-side heat dissipation. b Four cases of STEG with (I) no thermal management, (II) hot-side thermal management, (III) cold-side thermal management, and (IV) both sides thermal management. c Simulated STEGs’ peak output power with different thermal management strategies. d Simulated energy flows in the four STEGs. The blue bars represent the energy flow through the STEG
