Linear double-chain flexible film thermoelectric generator and preparation method thereof

The invention relates to a linear double-chain flexible film thermoelectric generator and a preparation method, and belongs to the field of thermoelectric power generation. Comprising a flexible substrate tiled on a flat rigid surface, a plurality of columns of holes distributed in the longitudinal direction of the flexible substrate, copper blocks matched with the holes and embedded in the holes, heat collection fins glued to the bottoms of the copper blocks and the back face of the flexible substrate, and heat dissipation fins laid between every two adjacent columns of copper blocks and glued to the front face of the flexible substrate. P-type thermoelectric materials and N-type thermoelectric materials are alternately arranged between the copper blocks in each row and the heat dissipation fins in the transverse direction of the flexible substrate, paste formed by silver is coated between the copper blocks at the head and the tail of the corresponding row in the longitudinal direction of the flexible substr
