Development of an advanced RTG using segmented thermoelectrics

Creators

Description

A 10% efficient radioisotope-heated thermoelectric generator (RTG) is being developed for the Department of Energy that consists of: (1) a radiation-coupled heat source; (2) a multi-series parallel circuit; (3) a very high specific weight radiator structure fabricated with graphite fiber and epoxy; and (4) segmented thermoelectric legs. For the positive (P) leg, (Cu,Ag)2Se is segmented with (Bi,Sb)2(Se,Te)3, PbSnMnTe, or (AgSeTe2)015 (GeTe)085 (TAGS). For the negative (N) leg, NdSe15 is segmented with PbTe. The operating hot temperature (H/sub H/ and cold temperature (T/sub C/) are 7250C and 1500C, respectively
