Tittle:
Efficient thermoelectric device for low-cost large-scale applications
Summary:
A Spanish university has developed an innovative organic thermoelectric device composed of a completely flexible semiconductor polymer for the production of energy in applications with large surfaces (e.g., on solar panels). The technology, which is patent pending, is useful in different sectors of energy and electronics: energy production, refrigeration or construction of intelligent buildings. Companies interested in green energy solutions for licensing or technical collaborations are sought.
Description:
Currently, there are thermoelectric coolers devices commercially available based on Bismuth telluride (Bi2Te3) - semiconducting metal alloy, called Peltier modules. They are used in refrigeration systems. The use of these devices for applications in large areas is completely impractical for its high cost. There are also some prototypes using n and p -type organic semiconductors, arranged alternately. Many of these devices have serious drawbacks, such as its low efficiency and low viability in scaling to large areas. Some thermoelectric conversion devices using a single type of organic polymeric semiconductors (poly-(3,4-ethylenedioxythiophene) (PEDOT), polyaniline (PANI), polypyrrole, etc) have been developed. They allow the possibility of incorporating a flexible substrate, where the polymer elements have vertically conformation. It allows the possibility of incorporating a flexible substrate, where the polymer elements have vertically conformation. However, these devices have the problem that it is always necessary to dissipate heat on the cold side to maintain an acceptable temperature difference, so much efficiency is lost. Furthermore, these thermoelectric materials are prepared by mechanical methods of coating. The manufacturing process is complicated as it contains numerous steps. It generates a considerable cost increase of the device. It is necessary to offer an alternative to the state of the art covering the gaps found, that is;.(i) Providing a thermoelectric device that improves the efficiency in relation to known devices.; (ii) Permitting the cold and hot parts to be far enough that avoids the need to dissipate heat from the cold side; and (iii) that it will be suitable for large-scale applications .

Accordingly, Spanish researchers, have developed a novel organic thermoelectric device composed of a completely flexible semiconductor polymer. It can be used for the production of energy in applications with large surfaces, such as walls and windows of buildings or on solar panels. The device is based on organic semiconductor thermoelectric junctions (PEDOT, PANI, polypyrrole, etc. ..), with conducting polymers with a single type of carriers (p-type or n-type). Its novelty lies in the planar geometry and the manufacture of thermoelectric legs of the device. These legs are made all at once, allowing energetic efficiency and economical manufacture on a large scale.

The main applications of the technology are in various sectors of energy and electronics. Energy production (from the heat). Refrigeration. Construction of intelligent buildings.
