NOVELTY - Thermoelectric module defining hot and cold sides comprises several P-type thermoelectric elements and N-type thermoelectric elements arranged in an array and insulated from each other with self adhering polyimide film. Contacts on cold and hot sides connect elements in an electric circuit.    USE - In thermoelectric generator.    ADVANTAGE - Electric power is generated from low power heat sources in the range of fraction of watt to few watts. Thermoelectric elements are connected in series-parallel circuit, so that the reliability is enhanced.    DETAILED DESCRIPTION - Contact on cold and hot sides of thermoelectric module comprises thin sputtered gold layer and gold tab welded or electroplated over sputtered layer. Alternately, contact comprises thin sputtered electrically conductive material layer and electrically conductive tab such as nickel-aluminum (Ni-Al) alloy welded or electroplated over sputtered layer. N-type elements comprise bismuth telluride doped with iodoform and P-type elements comprise bismuth telluride doped with lead. Each P-type element and N-type element has cross section of less than about 0.01 square inch or 0.0003 square inch and length of more than 0.5 inch. About 100 or 324 elements are connected in series or in series-parallel circuit. INDEPENDENT CLAIMS are also included for the following: (i) Small thermoelectric module making method which involves preparing pucks of N-type and P-type thermoelectric materials by preparing N-type alloy of solid solution of bismuth telluride (Bi2Te3) and 7-20 molecular percent of bismuth selinide (Bi2Se3) with a doping of about 0.1% iodoform. Bi2Te3 and Bi2Se3 and iodoform are melted in a quartz ampoule and alloy is removed and ground in an inert gas glove box to produce a powder which is then pressed in vacuum hot press to form an N-type puck. P-type puck is prepared by melting solid solution of 70-90 molecular percent of antimony telluride (Sb2Te3) and bismuth telluride with doping of about 0.1% lead, in a quartz ampoule. P-type puck is prepared similar to N-type puck. Thin plates are cut from N and P type pucks to produce N-type and P-type plates and the plates are stacked to produce alternating layers of N and P type plates with thin self adhering polyimide insulator film layer between each layer of plates. Stack of alternating insulated layers are pressed in a hot-press to produce pressed stack of alternating insulated layers. Thin plates from pressed stack of alternating layers are cut to produce insulated layered plates which are stacked to produce layers of insulated layered plates with a thin layer of self adhering polyimide insulator between each layer of insulated layered plates. Stack of insulated layer plates are pressed in hot-press to produce pressed stack of insulated layer plates which comprises an array of P-type and N-type thermoelectric elements arranged in checker board pattern and defines hot and cold sides. Electrical contacts are applied between P-type and N-type elements at hot and cold sides to connect elements in electrical circuit. One side of cold and hot sides of thermoelectric module is covered with photoresist. Pattern representing locations of gold contact pads or electric circuit connecting elements is placed over photoresist. Pattern covered photoresist is exposed to ultraviolet light to form soluble hardened photoresist portions. Pattern is removed and soluble photoresist portion is dissolved. Few microns thick of gold layer is sputtered through hardened photoresist portion onto cold and hot sides to form gold contact pads or electric circuit. Hardened photoresist portion is dissolved and gold tabs are welded on top of gold contact pads and repeating the required process for another side of cold and hot sides. A thin layer of gold except surface covered by gold tabs, is blasted away. Gold tabs are welded using parallel gap welding or laser welding, in which gold tabs are covered with transparent tool prior to laser welding. Thermoelectric module is electroplated after mask is removed from its cold and hot sides. Two electric leads are attached to appropriate positions on array of elements to produce thermoelectric module; (ii) Electric generator which consists of thermoelectric module and electrical leads attached to array of P-type and N-type thermoelectric elements.
