NOVELTY - Manufacture of thermoelectric component involves thermomechanically processing material (A) with powder (B). The material (A) is ball-milled before thermomechanical processing to form ball-milled powder (A) comprising cobalt silicide and dopant. The powder (B) comprises n-type filled skutterudite (802). The powder (B) is provided in contact with primary layer of ball-milled powder (A) and a secondary layer of ball-milled powder (A) before thermomechanical processing.    USE - Manufacture of thermoelectric component used for thermoelectric power generation devices e.g. solar thermoelectric energy converter and thermoelectric module.    ADVANTAGE - The method efficiently provides thermoelectric component having high electroconductivity, and improved thermal stress, parasitic thermal resistance and chemical stability, and capable of improving overall efficiency of existing apparatus and systems by recovering waste heat, for example from vehicle exhaust. Since the thermoelectric component recovers waste heat, the consumption of fossil fuels is reduced. The thermoelectric power generation device using the thermoelectric component operates without moving components, and is thus highly reliable.
