Semiconductor/display materials and devices

한양대 유기나노공학과 박희준 교수와 아주대 이재진 교수 공동연구팀이 유연한 '갈륨비소(GsAs) 화합물'에 '페로브스카이트 반도체'를 결합한 '탠덤 태양전지'를 개발했다.
갈륨비소 화합물 위에 쌓아올려 제작한 탠덤 태양전지는 기존보다 효율이 15% 이상 높은 것으로 나타났다.
가볍고 유연한 화합물 반도체 태양전지의 광전환효율을 높이기 위해 저가의 페로브스카이트를 활용한 탠덤 구조 태양전지 구현을 통해 비용 상승 부담을 완화했다.
장파장 빛을 흡수하는 화합물 반도체 결정 위에 단파장의 빛을 흡수하는 페로브스카이트 박막을 적층, 보다 다양한 파장의 빛을 활용하도록 함으로써 전기에너지 변환효율을 높이는 방식이다.
탠덤 태양전지는 자동차, 무인비행기, 웨어러블 기기는 물론 사물인터넷(IoT) 센서 에너지원 등으로 활용할 수 있을 것이다.
이 연구는 과학기술정보통신부, 교육부, 한국연구재단이 추진하는 기초연구사업 (중견연구 및 기본연구 등) 등의 지원을 받아 진행됐으며, 연구 결과는 국제 학술지 「Advanced Energy Materials」 2019년 12월 19일 자 표지논문으로 게재됐다.
