摘      要：By using a p-type (La, Ba, Ga, Ti)(1)(Fe, Co)(4)Sb-12 skutterudite with a dimensionless figure of merit, ZT, = 0.75 at 500A degrees C and an n-type (Yb, Ca, Al, Ga, In)(0.7)(Co, Fe)(4)Sb-12 skutterudite with ZT = 1.0 at 500A degrees C, we fabricated a thermoelectric power-generation module capable of working at high temperatures (up to 600A degrees C). When its hot and cold sides were at 600A degrees C and 30A degrees C, respectively, the power output of a 50 mm x 50 mm x 7.6 mm skutterudite module was 34 W and its thermoelectric conversion efficiency was 8%. In a durability test with the module s hot and cold sides continuously maintained at 600A degrees C and 80A degrees C, respectively, for 8000 h, power generation first decreased by approximately 6% in the initial 300 h then remained constant.
