摘要: Abstract Dye-sensitized solar cells (DSSCs) were fabricated using anthocyanin extracted from red cabbage ( Brassica oleracea var. capitata f. rubra ). Carbohydrates found to be excellent performance enhancers that functioned in a dose-dependent manner. Different types of carbohydrates generally had different enhancement capabilities the order oligosaccharide > disaccharide > monosaccharide > polysaccharide. The capability was also highly dependent on constituents carbohydrates. Two oligosaccharides, Isomalto-oligosaccharide (IMO) and xylooligosaccharide (XOS), showed highest capability. DSSCs sensitized with them as additives exhibited power conversion efficiency η ) over 1.6% (an improvement 60%) short-circuit current J SC about 4 mA/cm 2 , open-circuit voltage V OC around 630 mV. mode interaction extrinsic proposed discussed. use common coadsorbent deoxycholic acid (DCA) together could induce an additional enhancement, which boosted up 1.87% accumulative 90%). This study provided choice promising powerful enhancer for based natural anthocyanins.
