실리콘/그래핀 접합 태양전지의 장점은? | 35) 그래핀 전극을 통해 흡수된 빛은 그래핀/실리콘 접합면에서 전자와 정공으로 분리되어 N형의 실리콘쪽으로 전자가 흐르고 P 형 특성을 보이는 그래핀쪽으로 정공이 흘러 전하를 생성하고 생성된 전하는 그래핀 투명전극과 실리콘 하부 전극을 통해 포집된다. 그래핀 필름이 투명전극 역할뿐만 아니라, P 형 반도체 역할까지 동시에 수행하여 소자 구조를 단순화할 수 있는 장점이 있다. 태양전지 효율은 실리콘/그래핀의 접합면 특성과 그래핀 면저항값에 크게 좌우되기 때문에, 현재 그래핀의 전도도를 향상시키고 접합 특성을 개선하여 광전환 효율을 극대화하는 연구가 활발히 진행되고 있다. | |
그래핀이란? | 그래핀은 탄소원자의 강한 공유결합으로 형성된 단원자층으로 이루어진 2차원 평면 구조를 갖는 탄소 나노소재이다. 이러한 그래핀은 적층되면 3 차원의 흑연 (graphite)구조를, 말리면 1 차원 탄소나노튜브 (carbon nanotubes)와 0 차원의 공 모양(buckyball)을 이루는 물질로 다양한 저차원 나노 현상을 연구하는데 그동안 중요한 모델이 되어왔다. | |
그래핀 기반 투명전극은 어떤 분야에서 ITO를 대체할 수 있는가? | 그래핀 기반 투명전극은 터치센서, 태양전지, 조명소자와 반도체소자 등 다양한 분야에서 기존 투명전극 소재인 ITO의 대체 소재로서 응용될 수 있으며, 그래핀이 갖고 있는 우수한 기계적 물성을 이용하여 차세대 정보화기기로 등장할 플렉서블, 웨어러블 전자소자를 위한 플렉서블 투명전극 소재로의 활용이 기대된다. 그래핀이 학문적 연구 단계를 넘어서서 실제 상업화되기 위해서는 고품질의 그래핀 필름을 안정적으로 제조할 수 있는 기술개발이 필수적으로 요구되고 있다. |
