    Bhuiyan, MRA; Mamur, H; Dilmaç, ÖF
    Background: Future sustainable energy industrialization is a green energy source that has a lower circumstantial impact than traditional energy technologies. The advancement of new energy generation is important to expand the share of renewable energy sources. Objective: Worldwide, for the next generation, future energy demand may be fulfilled by using one of the renewable energy sources such as thermo electricity. Methods: The bismuth telluride-based (Bi2Te3-based) nanostructure material in thermo electricity still has a major part of applications. It is known as the most prospective TE device manufactured from a research arena towards successful commercialization. Results: The Bi2Te3-based nanostructure material is now on commercialization stages that it has some limitations. In order to find out the future direction of research and development of this material, the material will face a challenging way. Conclusion: The review paper provides an effective approach to overcome the limitation of Bi2Te3- based nanostructure. Moreover, in this review paper, the performance evaluation with existing Bi2Te3-based nanostructure and some other TE materials will be discussed in detail.

    Opportunities for thermoelectric generators in supporting a low carbon economy
    Bhuiyan, MRA; Mamur, H; Dilmaç, ÖF; Üstüner, MA
    Environmental pollution, global warming and increasing energy demands are urgent challenges facing society. Governments all over the world have set a national policy target for the transition to a zero or low carbon dioxide economy. As a result, scientists and engineers in industry and academia are working to develop cleaner, alternative and sustainable energy production technologies. One technology that has potential in this green technology transition is thermoelectric generators (TEGs), traditionally used off-grid and isolated from things such as stand-alone solar-thermal cells for military and aerospace applications such as missile-testing systems and space telescope cameras. However, future applications based on home entertainment, security systems and smart metering applications are imminent. Key limitations to this are low efficiency, high costs and self-heating with low thermal conductivity. Hence, this study aims to examine the current state of the art of TEGs and identify future research directions to achieve support for the green technology transition. The key findings of this study show that present successes will fulfill the future advancement of thermoelectric technology by supporting a low carbon dioxide economy.
