Although ZnO is a promising photoanode material for dye-sensitized solar cells (DSSCs), its efficiency is limited by charge recombination and structural instability. This study introduces, for the first time, hexamethylenediamine, hexylamine, and monoethanolamine as co-ligand capping agents for the hydrothermally growth of Al-Coco-doped ZnO (AZOCo) nanorods on 2D-ZnO nanosheets. XRD analysis confirmed hexagonal wurtzite crystallinity, while FESEM revealed a tunable nanorod morphology. Optical analyses indicated tunable band gaps (2.81-3.22 eV), enabling trap-assisted visible-light absorption. Al-Coco-doping with co-ligands reduced the charge-transfer resistance of ZnO nanosamples (110 k Omega) by 2-3 fold and significantly enhanced their long-term stability. AZOCo-99 %HMTA-1 %HMDA electrode exhibited remarkable corrosion resistance (J(cor)=36.4 nAcm(-2); V-cr=0.48 mu myear(-1)) with high N719 dye-loading (49 mgL(-1)). DSSCs based on this photoanode achieved a power conversion efficiency of 2.82 %, outperforming AZO-100 %HMTA (1.50 %) and ZnO-100 %HMTA (0.68 %). These results highlight Al-Coco-doping combined with co-ligand engineering as a powerful approach to fabricate high-performance, corrosion-resistant ZnO photoanodes for next-generation DSSCs.
