초록

본 연구에서는 열처리 온도(Pure: non-thermally treated, 450, 650, 850 oC)에 따른 P-25 광촉매의 특성 변화를 조사하였으며, 이 광촉매를 이용하여 염료 감응형 태양전지를 제조하고 그 효율 특성을 연구하였다. P-25 광촉매의 열처리 온도에 따른 Methylene blue의 광분해 정도는, Pure와 450~650 ℃에서 소성된 광촉매들의 광분해도는 3시간 이후 약 97~99%로 비슷한 결과를 보였고, 850 ℃에서 소성된 광촉매는 약 46%로 다른 광촉매에 비해 낮은 값을 보였다. 비열처리(Pure) 광촉매와 450, 650, 850 ℃에서 열처리한 광촉매를 이용하여 제조한 염료감응형 태양전지의 에너지 변환 효율은 각각 6.9, 6.5, 5.8 그리고 5.6%로 각각 나타났다.

In this study, the variation of characteristics of P-25 photocatalyst with calcination temperature(Pure: nonthermally treated, 450, 650, 850 ℃) was studied. The photocatalysts were used as working materials for dye-sensitized solar cells: DSSCs) later on and their photovoltaic characterization was carried out. The photocatalytic degradation of methylene blue using the P-25 photocatalyst with different calcination temperature was almost same expect for 850 ℃. The solar energy conversion efficiency (η) of DSSCs prepared by the nanoparticles (photocatalyst) reached 6.9% (for pure), 6.5%(for 450), 5.8%(for 650) and 5.6%(850).
