Effects of anchoring groups on perylenemonoimide-based sensitizers for p-type dye-sensitized solar cells and photoelectrochemical cells

Two metal-free sensitizers (YK-1 and YK-2) with carboxyl and hydroxamate acid anchoring groups were successfully applied in p-DSCs and PECs, where YK-2 achieved a higher photocurrent of 6 µA cm−2 under alkaline aqueous conditions in PECs.115.
