Abstract
본 연구에서는 건식플라즈마 환원방법을 이용하여 다중벽 탄소나노튜브(MWNT) 코팅 층 위에 백금, 금, 백금/금 이종나노입자를 쉽고 균일하게 고정화 시킬 수 있는 방법을 제시한다. 나노입자는 다중벽 탄소나노튜브 위에 안정적이고 균일하게 고정화되어 나노하이브리드 소재가 되며, 이렇게 합성된 나노하이브리드 소재는 염료감응형 태양전지의 상대전극에 적용된다. CV, EIS, Tafel 측정을 통해 준비된 상대전극의 전기화학적 특성을 분석한 결과, PtAu alloy/MWNT 상대전극이 가장 높은 전기화학적 촉매 활성과 전기 전도도를 보여준다. PtAu alloy/MWNT 상대전극을 이용한 염료감응형 태양전지는 7.9%의 에너지 변환 효율을 보임으로써 MWNT (2.6%), AuNP/MWNT (2.7%) 그리고 PtNP/MWNT (7.5%) 상대전극을 사용한 염료감응형 태양전지의 효율과 비교하였을 때, 가장 높은 효율을 보여주고 있다.
In this study, we present an excellent approach for easily and uniformly immobilizing Pt, Au and bimetallic PtAu nanoparticles (NPs) on a multi-walled carbon nanotube (MWNT)-coated layer through dry plasma reduction. The NPs are stably and uniformly immobilized on the surface of MWNTs and the nanohybrid materials are applied to counter electrode (CE) of dye-sensitized solar cells (DSCs). The electrochemical properties of CEs are examined through cyclic voltammogram, electrochemical impedance spectroscopy, and Tafel measurements. As a result, both electrochemical catalytic activity and electrical conductivity are highest for PtAu/MWNT electrode. The DSC employing PtAu/MWNT CE exhibits power conversion efficiency of 7.9%. The efficiency is better than those of devices with MWNT (2.6%), AuNP/MWNT (2.7%) and PtNP/MWNT (7.5%) CEs.
