“…Nonetheless, it is noticeable the increase of the V oc in the devices prepared with Cx-2-AT-L; this result can be explained due tothe cone scaffold that could inhibit the dark current caused by the recombination of the TiO 2 conduction band electrons with I 3 -. [19,20,31,32] When dyes with different linkage location are compared, it is observed that the dye loading of the sensitizer with the alkyl linkage on the donor part, Cx-2-AT-L (1.92 10 -7 ),is slightly higher than the loading of dyes with the linkage on the π-spacer, Cx-2-TPA(1.30 10 -7 mol/cm 2 ). [19] Moreover, due to the absorption characteristics of these dyes, the IPCE spectrum of the device prepared with Cx-2-AT-L is broader than the one of Cx-2-TPA.…”
