Performance

The TIG-BiTe-P/N-2 thermoelectric ingot is grown with the alloy of Bi, Sb, Te, Se, special doping and our unique crystallizing processes. The Bi2Te3-based thermoelectric ingot is grown specially and optimized for making the thermoelectric modules that used for converting heat source ranging from 100℃(373K) to 350℃(623K) into electricity . Generally, the average figure of merit ZT of our p-type and n-type ingots over the temperature range 300K to 600K is larger than 0.7. The module made with such ingots can achieve 5% efficiency with 250℃ Delta T. Meanwhile, our ingot is featured with good mechanical strength and highly stable property, providing the key stone for producing the high performance and reliable power generation modules.
