초록

III-V족 화합물반도체 기반의 다중접합 태양전지는 광전변환 효율이 매우 높고 내열, 내방사선 특성이 우수하여 인공위성이나 우주 탐사선의 태양광 패널에 주로 활용되어 왔다. 최근에는 III-V 태양전지의 활용범위가 지상 발전용으로 점차 확대되고 있으며, 가격 경쟁력 확보를 위한 고효율화 기술과 저가화 기술이 활발히 연구되고 있다. 본고에서는 현재 세계 최고 효율(46%)을 기록하고 있는 집광형 III-V 태양전지와 무인 항공기 및 전기 자동차의 보조 동력원으로 주목받고 있는 플렉시블 III-V 태양전지의 국내외 연구동향을 소개하고, 초고효율 III-V 태양전지의 향후 전망에 대해 논의하고자 한다.
