Dye-sensitized solar cells (DSSCs) have received tremendous attention recently. Among the various approaches to tune the property of organic dyes based on D-p-A structure, variation of the p-linkers has been commonly used.1 The influence of dipole moment has been much less studied. To this end, we synthesized two new dyes, 28  and 29  (Figure 1), that are isomers with different dipole moments. Their optical properties and photovoltaic performance (e.g., absorption, power conversion efficiency, Voc, Jsc, etc.) have been evaluated and compared. Experimental details and calculation results will be presented. References (1)   Hagfeldt, A.; Boschloo, G.; Sun, L. C.; Kloo, L.; Pettersson, H. Chem. Rev. 2010 , 110, 6595.
