The thermoelectric materials are the most critical working component of the device. The ZT of the material is the most important primary determinant of thermoelectric conversion efficiency. Hence, the demand for higher ZT materials is the critical barrier for the growth of the thermoelectric device market. Other significant factors, ranked in order of importance, are: costs, mechanical integrity, compatibility with existing infrastructure, and ease of handling. Our high-ZT materials products directly address this industry primary need of higher energy conversion efficiency than offered by the current state of the art, with scope for continuous improvement through product optimization. Bismuth telluride alloys are the only current choice for near-room-temperature devices and account for virtually the entire global thermoelectric market space. No known alternatives are available to replace bismuth telluride and higher ZT bismuth telluride alloys obtained through nanostructuring by our innovation can be easily adopted by the industry with minimal changes in infrastructure, thus meeting the secondary needs.
