A novel class of dyes, namely benzoporphyrins, was synthesized and implemented into dye‐sensitized solar cells. They feature complementary absorptions compared to N719, which renders them promising candidates for co‐sensitization in DSSCs. Notably, metallated benzoporphyrins reveal a TiO2–nanoparticle attachment that is size and aggregation dependent. Therefore, unproductive energy‐transfer events
合成了一类新型染料,即苯并卟啉,并将其应用于染料敏化太阳能电池。与N719相比,它们具有互补吸收,这使其成为有前途的DSSC共敏候选物。值得注意的是,金属化的苯并卟啉显示出TiO 2-纳米颗粒附着,这取决于大小和聚集。因此,可以防止选择性连接的染料之间发生非生产性的能量转移事件。鉴于后者,在将苯并卟啉和N719选择性吸附到TiO 2光电极的不同层上时,效率提高了39%。
