The heat recovery with thermoelectric devices is seen as part of the solution for a more sustainable world. However, the actual commercial systems are based on modules having expensive and/or toxic elements, with high materials production costs, making them unsuitable for an extensive use. Consequently, the discovery and development of easy-to-make materials mainly containing earth-abundant, low-cost and low toxic elements, is highly desirable.
Tetrahedrites are world spread Cu sulfosalt minerals, with (Cu,M)12Sb4S13 (M = Fe,Ag,Zn) general composition. Recently, mineral-based and synthetic tetrahedrite materials were considered with good potential for thermoelectric applications.
In this talk studies on the use of tetrahedrites as sustainable thermoelectric materials are presented. Emphasis is done on the raw material prices evaluation, on the feasibility of rapid, scalable, cheap tetrahedrite synthesis and on their long term stability under working conditions.
