摘要：In this work, two new dyes YK-1 and YK-2 with carboxylic acid and hydroxamic acid as anchoring groups,respectively, in combination with diphenylamine as donor and perylenemonoimide as acceptor were synthesized and applied in p-type dye-sensitized solar cells（p-DSCs） and dye-sensitized photoelectrochemical cells（PEC）. The results showed that the sensitizer（YK-1） based on carboxylic acid displayed a higher conversion efficiency of 0.064% under AM 1.5 solar conditions in p-DSCs. However, it was interesting that the hydroxamic acid based sensitizer（YK-2） on Ni O photocathode displayed better performance in a hydrophilic environment over a broad p H range under visible-light irradiation because of a versatile covalent attachment to Ni O surfaces. This may be ascribed to hydroxamic acid anchors, which have more sites interacting with the surface of Ni O in aqueous solution. This study demonstrates that YK-2 containing hydroxamic acid anchoring group is a promising candidate to achieve highly efficient and stable activity for dye-sensitized PEC system.
