초록
실리콘 태양전지와 비교해 제조비용이 저렴하고 뛰어난 안정성을 가지고 있는 염료 감응 태양전지에 관한 다양한 연구가지속적으로 이루어지고 있다. 본 연구에서는 TiO와 NbO을 혼합하여 만든 반도체 산화물을 사용하여 염료 감응 태양전지의 특성을 연구하였다. NbO을 서로 다른 비율로 첨가하여 태양전지를 제작하였고, 이에 따른 표면적, 전기적 특성을 측정하였다. NbO가 첨가될수록 염료 및 전해질의 접촉 면적이 증가하게 되었고, 이에 따라 염료 감응 태양전지의 단락 전류,개방전압, 곡선인자 및 변환 효율이 개선됨을 확인하였다.
Abstract
Various studies on dye-sensitized solar cells, which are cheaper to manufacture and have superior stability than siliconsolar cells, are continuously conducted. In this study, the properties of dye-sensitized solar cells were studied usingsemiconductor oxides made by mixing TiO and NbO. By adding NbO in different proportions, the solar cell wasmade, and the surface area and electrical characteristics of this cell were measured. As NbO was added, the contactarea of dye and electrolyte increased and the short-circuit current, open voltage, fill factor and conversion efficiency ofdye-sensitized solar cells were confirmed to be improved.
