N2 - In this study, we report a new BODIPY-based design, called the cross-conjugated design, that takes advantage of the α- and β-position functionalization of the BODIPY core. After synthesis, and compared to a more standard BODIPY dye, using similar functional groups and based on a horizontal design, called h-BOD, the new cross-conjugated BODIPY dye (cc-BOD) exhibits clearly the highest conjugation and light harvesting properties. Consequently, when used as photosensitizers in dye-sensitized solar cells (DSSCs), an impressive improvement of power conversion efficiency (PCE) has been observed, with a PCE of 6.02% with broad incident photon to current conversion efficiency (IPCE) for cc-BOD, compared to only 3.7% for h-BOD. Moreover, by co-sensitizing a DSSC with the two complementary absorbing dyes h-BOD and cc-BOD, we further improved the PCE up to 6.2%.
