dc.description.abstract | We report a novel way to accelerate the rate of oxidized sensitizer neutralization on nanocrystalline TiO2 electrode surfaces using a novel coadsorbent, 3,4,5-tris-butenyloxy benzoic acid (TD), having three terminal double bonds. H-1 NMR and contact angle measurements revealed that the terminal double bonds reacted with I-2 to form an in situ-generated ionic layer of I- species. Transient absorption spectroscopy (TAS) and electrochemical impedance spectroscopy (EIS) studies demonstrated that I- species neighbouring the cationic dye molecules (D+) accelerate the neutralization (or regeneration) rate (k(D+)), as well as decrease the recombination reactions of photoinduced electrons with D+ (k(1)) and I-3(-) (k(2)). Dye-sensitized solar cells treated with TD exhibit a power conversion efficiency of 10.2%, which is 22% higher due to the simultaneous improvements in J(SC) and V-OC, even at 15% low dye loading levels, compared to the values obtained from a conventional device. | - |
