Tetrahedrites are natural earth-abundant minerals consisting of environmentally-friendly elements of copper and sulphur. Recently, research has been focused on the natural and synthetic minerals of tetrahedrite materials for thermoelectric applications. The thermoelectric figure of merit zT of around unity at similar to 723 K for many doped and natural tetrahedrite materials in the past 2-3 years was determined and this value is comparable to conventional p-type TE materials. In this review, a brief history of tetrahedrite materials is followed by information about its crystal structure and chemical bonding, electronic band structure and transport properties. Different synthesis approaches have been summarized. Also, this review outlines the effect of different doping elements on the thermoelectric properties of tetrahedrite materials, and the natural mineral tetrahedrite that can be used as thermoelectric materials.
