요 약. 염료감을 태양전지(DSSC)는 대체에너지 집적제로서 낮은 생산단가로 고에너지 전환 효과를 볼 수 있다. 친환경 적이며 효과가 큰 무금속 염료감응제의 개발이 중요하다. 본 연구에서 유기 감광제로주제어: 유기염료 감응제, 집광 소재, 염료감응 태양전지 ABSTRACT. Dye-sensitized solar cell (DSSC); an alternate energy source harvester has gained some attractive features such as high-energy conversion efficiency low production cost. Dye-sensitizer is a basic component of DSSC, which affecting the performance of the energy conversion efficiency. Current research has been focusing on development of high efficiency, metal-free dye-sensitizers, which would be more environmental friendly. We had successfully explored synthetic route to 6,6'-(1,2,5-oxadiazole-3,4-diyl)dipyridine-2,4-dicarboxylic acid (3A) which has been used as organic sensitizer. Investigation of light conversion efficiency (η) of the compound uses standard measurement condition (one sun simulated irradiation, AM 1.5, 100 mW/cm 2 ) showed that it could reach 1.00% (JSC=2.63 mAcm -2 , VOC=0.64 V and FF=0.59). Under the same conditions, the ruthenium complex (N719) gave the conversion efficiency as high as 4.02%(JSC=10.50 mAcm -2 , VOC=0.67V and FF=0.57).

Synthesis and Application of Natural Dye Sensitizd CDS Thin Films as Photoanode for DSSC

“…Generally, transition metal coordination compounds such as Ru-polypyridyl complexes and pure organic dyes are used as sensitizer due their good light harvesting property and stability [3][4][5][6][7][8]. However, application of these types of sensitizers also faced problems regarding complicated synthetic routes, low efficiency and most importantly use of environmentally non-benign chemicals.…”
