What is Bismuth telluride?
Bismuth telluride (Bi 2Te 3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth(III) telluride. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation.. They are also the best materials for use in thermoelectric generators when the temperature of the heat source is moderate. Bismuth telluride is the dominant thermoelectric material for applications near room temperature due to its inherently low lattice thermal conductivity and high electronic weighted mobility.

Materials that are composed of p-type bismuth telluride, which are suitable for low-temperature power generation (near 380 K), were successfully obtained through Sb-alloying, which suppresses detrimental intrinsic conduction at elevated temperatures by increasing hole concentrations and material band gaps.
What are the side effects of bismuth crystal?
Bismuth and its salts can cause kidney damage, although the degree of such damage is usually mild. Large doses can be fatal. Industrially it is considered one of the less toxic heavy metals. For infinite-cascade devices, a thermoelectric efficiency larger than 33% (≈1/3) is achievable when ℎ exceeds 1400 K. For single-stage devices, the best efficiency of 17.1% (≈1/6) is possible when ℎ is 860 K. Purified tin selenide in polycrystalline form — outperforms the single-crystal form in converting heat to electricity, making it the most efficient thermoelectric system on record. Alphabet claims that the E1 is the world's most powerful thermoelectric generator. Hot exhaust is piped from the diesel generator into the E1 and passed through thirty-two TEG modules.
Is bismuth technically radioactive?
Bismuth was long considered the element with the highest atomic mass whose nuclei do not spontaneously decay. However, in 2003 it was discovered to be weakly radioactive. Bismuth has been used in solders, various other alloys, metallurgical additives, medications and atomic research. Most 95 million cars produced annually contain about 2 ounces of bismuth in the windshield frit. This black compound around the edge of the glass protects the adhesive that secures the windshield to the vehicle. As a result, Silicon-germanium alloys are currently the best thermoelectric materials around 1000 °C. Therefore, they are used in some radioisotope thermoelectric generators (RTG) (notably the MHW-RTG and GPHS-RTG) and other high-temperature applications, such as waste heat recovery.
