This work reports on the preparation of surface-modified TiO2 photoanodes by dip coating process and effects on the performance of dye-sensitized solar cells(DSSCs). Nanoporous TiO2 photoanodes were immersed into an aqueous 1,2-ethane disulfonic acid disodium salt (ED2S) solution, and the resulting phtoanodes were applied to DSSCs. DSSC with ED2S-modified photoanode showed an enhancement in open circuit voltage and short circuit current, resulting in a power conversion efficiency (PCE) of 7.37% compared to that (7.08%) of reference device with bare TiO2. |
