Three novel organic dyes coded as FHD4‐1, FHD4‐2, and FHD4‐3 featuring spiro[dibenzo[3,4:6,7]cyclohepta[1,2‐b]quinoxaline‐10,9′‐fluorene] (SDBQX) moieties are designed to inhibit dye aggregation to improve the performance of dye‐sensitized solar cells (DSSCs). The consistent absorption onsets of FHD4‐1, FHD4‐2, and FHD4‐3 in solutions and adsorbed on TiO₂ films indicate that these dyes are aggregation‐free dyes. Therefore, coadsorption with chenodeoxycholic acid (CDCA) of these three dyes reduces the performance of DSSCs because no inhibition effect for dye aggregation is needed, but, on the contrary, the dye loading amount is reduced after addition of CDCA.

用于染料敏化太阳能电池的无聚集有机染料，具有螺[二苯并[3,4:6,7]环庚[1,2-b]喹喔啉-10,9'-芴] (SDBQX)。

编码为FHD4-1、FHD4-2和FHD4-3的三种新型有机染料，具有螺[二苯并[3,4:6,7]环庚基[1,2- b ]喹喔啉-10,9′-芴]（SDBQX）部分旨在抑制染料聚集，以提高染料敏化太阳能电池（DSSC）的性能。FHD4-1、FHD4-2和FHD4-3在溶液中和吸附在 TiO ₂薄膜上的一致吸收起始表明这些染料是无聚集染料。因此，这三种染料与鹅去氧胆酸（CDCA）的共吸附降低了DSSC的性能，因为不需要染料聚集的抑制作用，但相反，添加CDCA后染料负载量减少。
