A thermoelectric generator apparatus disposed on a high-temperature surface of an object (as a heat source), at least includes a heat concentrator, a thermoelectric module and a cold-side heat sink. The heat concentrator has a top surface and a bottom surface contacting a high-temperature surface of the object, and an area of the bottom surface is smaller than that of the high-temperature surface. The thermoelectric module is disposed on the top surface of the heat concentrator. The cold-side heat sink is disposed on the thermoelectric module. Heat generated by the heat source is concentrated on the heat concentrator and flows to the hot side of the thermoelectric module for increasing the heat flux (Q′) passing the thermoelectric module and the hot side temperature of the thermoelectric module. Consequently, the thermoelectric conversion efficiency (η) is improved, and the power generation of the thermoelectric module is increased.

A thermoelectric device at least includes a ring-shaped insulated substrate and plural sets of thermoelectric thin film material pair (TEP) disposed thereon. The ring-shaped insulated substrate has an inner rim, an outer rim and a first surface. The sets of TEP electrically connected to each other are disposed on the first surface of the ring-shaped insulated substrate. Each set of TEP includes a P-type and an N-type thermoelectric thin film elements (TEE) electrically connected to each other. Also, the N-type TEE of each set is electrically connected to the P-type TEE of the adjacent set of TEP. When a current flows through the sets of TEP along a direction parallel to the surfaces of P-type and N-type thermoelectric thin film elements, a temperature difference is generated between the inner rim and the outer rim of the ring-shaped insulated substrate.

A solid-liquid interdiffusion bonding structure of a thermoelectric module and a fabricating method thereof are provided. The method includes coating a silver, nickel, or copper layer on surfaces of a thermoelectric component and an electrode plate, and then coating a tin layer. A thermocompression treatment is performed on the thermoelectric component and the electrode plate, such that the melted tin layer reacts with the silver, nickel, or copper layer to form a silver-tin intermetallic compound, a nickel-tin intermetallic compound, or a copper-tin intermetallic compound. After cooling, the thermoelectric component and the electrode plate are bonded together.
