The influence of LiNO(3)incorporation onto TiO(2)electrodes on the performance of dye-sensitized solar cells (DSSCs) was studied. LiNO3-incorporated TiO(2)electrodes were prepared by a dip coating process and the resulting electrodes were applied to DSSCs. Open circuit voltage (V-oc) of DSSC with a LiNO3-modified TiO(2)layer was averagely improved by over 24% compared to that of a reference device with bare TiO2. The conduction band edge shift of TiO(2)to a negative direction, arising from the formation of a surface dipole, accounted for the improvement in V-oc.
