Both the steady-state absorption spectrum and excited state dynamics are influenced by the side-group substitution, and the changes are rationalized based on shifting of the lowest metal-to-ligand charge-transfer (MLCT) state in energy based on the electron-withdrawing or electron-donating properties...
(as a consequence of the higher Voc and Jsc) was observed; this phenomenon, with an increase up to 26%, was explained by an enhanced solubility of the deprotonated species, causing a more efficient binding of the dye molecules on the TiO2 surface and leading to better electron transfer. The...
