염료감응형 태양전지 광전극의 초음파 열처리를 통한 광전효율 개선에 관한 연구

다국어 초록 (Multilingual Abstract)

A making process of DSC(dye sensitized solar cell) was presented. In general, Photo electrodes of DSC was made by using colloid paste of nano TiO₂ and processing of Doctor-blade printing and high temperature sintering for porous structure. These methods lead to cracks on TiO₂ surface and ununiform of TiO₂ thickness. This phenomenon is one factor that makes low efficiency to cells. After TiO₂ printing on TCO glass, a physical vibration was adapted for reducing ununiform of TiO₂ thickness. And a thermal treatment at Low temperature(under 75℃) was adapted for reducing cracks on TiO₂ surface.
In this paper, we have designed and manufactured an ultrasonic circuit (100W, frequency and duty variable) and a thermal equipment. Then, we have optimized forcing time, frequency and duty of ultrasonic irradiation and thermal heating for surface treatment of photo-electrode of DSC. In I-V characteristic test of DSC, ultrasonic and thermal treated DSC shows 19% improved its efficiency against monolithic DSC. And it shows stability of light-harvesting from drastically change of light irradiation test.
