英文摘要	4-(benzo[c] [1,2,5]thiadiazol-4-ylethynyl)benzoic acid (bteba) as a promising electron acceptor has been used in the highly efficient organic dye-sensitized solar cells (dscs) recently. because of its strong electron deficient character, bteba could bring forth a remarkable decline in the energy level of the lowest unoccupied molecular orbital (lumo) and further reduce the energy gap of dye molecules significantly. in this contribution, two metal free organic dyes wef1 and wef2 were synthesized by simply combining bteba with two slightly tailored electron-releasing moieties: 4-hexylphenyl substituted indaceno[1,2-b:5,6-b']dithiophene (idt) and cyclopenta[1,2-b:5,4-b'] dithiophene [2', 1' :4,5] thieno [2,3-d] thiophene (cpdtdt), which were screened rationally from an electron-donor pool via computational simulation. with respect to those of weft, wef2-sensitized solar cells demonstrate a far better short-circuit photocurrent density (j(sc)) and open-circuit photovoltage (v-oc), resulting in a similar to 50% improved power conversion efficiency of 10.0% under irradiance of 100 mw cm(-2) am1.5g sunlight. we resorted to theoretical calculations, electrical measurements, steady-state, and time-resolved spectroscopic methods to shed light on the fatal influences of elaborately modulating electron donors on light absorption, interfacial energetics, and multichannel charge-transfer dynamics.
