초록

본 연구에서는 전해증착법과 열처리를 통하여 ITO 투명전극 위에 고밀도의 ZnO 막대구조를 형성하는 방법을 조사하였다. 증착과정에서 $Zn(OH)_2$와 ZnO가 함께 형성되는 것을 고려할 때 전기화학적 ZnO 증착효율은 33% 이하를 나타내었다. $500^{\circ}C$ 열처리 후 ZnO는 (002)를 선택적으로 갖는 결정구조를 형성하며, 나노막대 구조의 성장속도는 0.986 ${\mu}m/hr$로 측정되었다. 그리고 전기화학적으로 제조한 ZnO 막대를 염료감응 태양전지의 전극으로 사용시 측정된 전지효율은 0.21%로서 태양전지용 전극으로서의 가능성을 확인하였다.

High density of ZnO nanorods were fabricated by electrochemical deposition and subsequent heat treatment. Formation of $Zn(OH)_2$ and ZnO during electrodeposition indicated that the electrodeposition efficiency of ZnO was below 33%. ZnO rod has a preferential (200) growth plane after heat treatment at $500^{\circ}C$ and the growth rate of ZnO rod was measured to be 0.986 ${\mu}m/hr$. Dye sensitized solar cell(DSC) showed the efficiency of 0.21% when electrochemically prepared ZnO rod was used as an electrode. It suggests the possible application of ZnO rod structure in the DSC.
