A hydroxamic acid group has been employed for the first time as an anchoring group for cobalt-based dye-sensitized solar cells (DSSCs). The porphyrin dye YD2-o-C8HA including a hydroxamic acid anchoring group exhibited a power conversion efficiency (η) of 6.4 %, which is close to that of YD2-o-C8, a representative porphyrin dye incorporating a conventional carboxylic acid. More importantly, YD2-o-C8HA was found to be superior to YD2-o-C8 in terms of both binding ability to TiO and durability of cobalt-based DSSCs. Notably, YD2-o-C8HA photocells revealed a higher η-value (4.1 %) than YD2-o-C8 (2.8 %) after 500 h illumination. These results suggest that the hydroxamic acid can be used for DSSCs with other transition-metal-based redox shuttle to ensure high cell durability as well as excellent photovoltaic performance.
异羟肟酸基团首次被用作钴基染料敏化太阳能电池（DSSC）的锚定基团。包含异羟肟酸锚定基团的卟啉染料YD2-o-C8HA的功率转换效率（η）为6.4%，这与包含传统羧酸的代表性卟啉染料YD2-o-C8相近。更重要的是，发现YD2-o-C8HA在与TiO的结合能力和钴基DSSC的耐久性方面均优于YD2-o-C8。值得注意的是，在光照500小时后，YD2-o-C8HA光电池显示出比YD2-o-C8（2.8%）更高的η值（4.1%）。这些结果表明，异羟肟酸可用于带有其他基于过渡金属的氧化还原穿梭体的DSSC，以确保高电池耐久性以及优异的光伏性能。
