electron‐withdrawing thiazole moiety with a catechol anchoring group would improve its photovoltaic performance. Herein, we report a push‐pull porphyrin sensitizer ZnPTC with a thiazolocatechol anchoring group. The DSSC with ZnPTC exhibited η=4.87 %. This value is the highest ever reported for catechol‐anchor based DSSCs. Meanwhile, the long‐term cell durability was not improved, although the robust anchoring
采用五元双齿螯合的锚定基团对于实现
染料敏化太阳能电池(DSSC)的高功率转换效率(η)和长期耐久性具有吸引力。在这方面,我们选择了
邻苯二酚作为可以采用螯合的锚定基团。但是,含
邻苯二酚敏化剂的DSSC从未超过2%的η值。这些不良的光伏性能可能与
邻苯二酚中羟基的供电子能力有关。考虑到这些,我们设想将吸电子的
噻唑部分与
邻苯二酚锚定基团融合将改善其光电性能。在本文中,我们报道了带有
噻唑邻苯二酚锚定基团的推挽
卟啉敏化剂Zn
PTC。DSSC与Zn
PTC表现出η= 4.87%。该值是基于
邻苯二酚的DSSC报告的最高值。同时,尽管在苛刻的条件下仍具有强大的锚固性能,但长期电池的耐久性并未得到改善。
