Thermoelectric (TE) power generation can provide a unique solution to convert waste heat into electricity. Generally, TE conversion efficiency depends on the material properties and design of the module structure. However, despite the development of highly efficient TE materials, module engineering is rather less advanced, restricting the available design of modules to that of planar structures. Herein, I present the development of the 3D printing process applied to a range of different TE materials. Surface states of TE particles were precisely optimized with the controllable charge states in the presence of anionic inorganic binders, achieving the suitable viscoelasticity of the TE inks to the extrusion-based 3D printing. The geometrically designed 3D-printed TE materials were assembled into power generating systems, in which high efficiencies of energy conversion were achieved. |
