High performance lead-free p- and n-type segmented thermoelements which are designed to produce electric power at 10% conversion efficiency were developed. The p-type element consists of newly developed zinc-antimony compound (Zn₄Sb₃) and bismuth-antimony-telluride ((Bi,Sb)₂Te₃) while the n-type consists of Skutterudite compound (CoSb₃) and bismuth telluride (Bi₂Te₃) based material. Zn₄Sb₃ exhibits superior performance over PbTe based material, which has been regarded as the best material for power generation.

A simulation software for thermoelectric power generation has also been developed to accelerate the development of the segmented thermoelements. The software has proven to be a powerful tool for designing thermoelectric modules.
