초록

인구 증가와 문명 발전에 따른 에너지 고소비형 사회로 진행됨에 따라 기존에 사용하던 에너지원의 고효율화 방안이 강구되고 있다. 이 중 열에너지 고효율화 방안으로 열전발전 기술이 주목을 받고 있다. 현재 열전발전 분야는 나노기술 등이 발전함에 따라 폐열회수 분야 등에서 충분한 경쟁력을 가질 수 있는 ZT > 2를 도달하였고, 더 높은 효율을 갖는 소재 개발 연구가 진행되고 있다. 본 총설에서는 현재 진행되고 있는 온도영역별 열전발전 소재 개발 및 모듈기술에 대해 간략히 소개하고자 한다.

Following the population growth and civilization, resulted in energy-mass consumption society, research efforts on enhancing efficiency of traditional energy sources has been investigated. Among many alternatives, thermoelectric power generation technologies are highlighted as one of solutions for high heat energy efficiencies. Currently, the research area of thermoelectric power generation has been achieved over two of ZT value, which seems to have enough competitiveness as following the development of nano-technologies, in particular, for waste heat recovery, and the development of thermoelectric materials is still ongoing to obtain higher energy efficiencies. In this review, the recent development of thermoelectric materials and module technologies categorized by different temperature regions was briefly introduced.
