Abstract

PEC전지 전극으로 사용될 수 있는 CdSe는 수용액상에서 광부식이 심하기 때문에 투명한 보호막이 필요하다. TiO2는 광부식이 심한 광전극의 보호막으로 적당하며 이 논문에서 화학적 방법(전기증착과 화학조증착)을 이용하여 산성용액이나 알칼리용액에서 TiO2 박막을 제조하여 광흡수나 광전류를 측정하였다. XRD를 이용해서 제조된 TiO2 박막의 결정성을 확인하였으며 막의 표면특성은 SEM으로 측정하였으며 광흡수 특성이 관찰되었다. 제조된 TiO2 박막의 광전류는 100 mw/cm2의 광세기를 가지는 제논 램프를 이용하여 측정하였다. CdSe에 TiO2박막을 코팅했을 때의 CdSe막의 광흡수와 광전류를 측정하여 TiO2 코팅효과를 관찰하였다.
