| 中文摘要 | in view of the limited ruthenium resource, metal-free organic dyes may play a prominent role in the coming large-scale application of cost-effective dye-sensitized solar cells, if their efficiency and stability can be considerably improved. in this paper we utilized a binay pi-conjugated spacer of ethylenedioxythiophene and dithienosilole to construct a high molar absorption coefficient push-pull dye, characteristic of an intramolecular charge-transfer band peaking at 584 nm measured in chloroform. in comparison with the standard ruthenium sensitizer z907, this metal-free chromophore c219 endowed a nanocrystalline titania film with all evident light-harvesting enhancement. leading to an unprecedented 10 0- 10 3% efficiency at the am 1 5g conditions for dye-sensitized solar cells with nonruthenium dyestuffs, although a highly volatile electrolyte was used. transient absorption measurements have revealed that even if the kinetics of back-electron transfer and dye regeneration am considerably different for z907 and c219, the branching ratios of these two charge-transfer channels are over 35 for both dyes, ensuring a high yield of net charge separation at the titania/dye/electrolyte interface. a solvent-free ionic liquid cell with c219 as the sensitizer exhibited an impressive efficiency or 8 9% under a low light intensity of 14.39 mw cm(-2), making it very favorable for the indoor application of flexible dye-sensitized solar cells. |
