Abstract

In this work, we consider the fabrication method and electrical characteristics of dye-sensitized solar cells (DSSCs), which use titanium (Ti) metal thin films to replace expensive fluorine tin oxide (FTO) electrodes. The thickness of the Ti thin film was changed by adjusting the deposition time of the Ti, and the surface resistance decreased as the thickness of the Ti thin film became thicker. The thickness of the Ti thin film was shown to be similar to the surface resistance of the FTO thin film at approximately 190nm and the DSSC with a thickness of approximately 250nm showed the highest energy conversion efficiency of 4.24%. Furthermore, the possibility of commercialization was confirmed by fabricating and evaluating the DSSC module.

본 연구에서는 티타늄(Ti) 금속 박막을 사용해서 값비싼 산화주석(FTO) 전극을 대체된 염료감응형 태양전지(DSSC)의 제작 방법과 전기적 특성에 대해서 고찰하였다. Ti 박막의 증착 시간을 조절하여 박막의 두께를 변화시켰으며, Ti 박막의 두께가 두꺼워지면서 표면저항은 감소하였다. 대략 190nm 두께에서 FTO 박막의 표면저항과 비슷해짐을 알 수 있었으며, 250nm 두께에서 DSSC의 에너지 변환효율 4.24%로 가장 높았다. 더 나아가 DSSC 모듈을 제작해 평가함으로써 상용화의 가능성을 확인하였다.
