Acid boric can thoroughly leads to the hierarchical porous titania structure. Boron is introduced into titania lattice which causes slight blueshift of bandgap. The optimized sol parameters are H3BO3/TTiP = 0.45, DI/TTiP = 4.5, and 0.17 M. Optimized paste parameters is not changed compared to conventional pastes. The DSSC based on H3BO3 catalyzed sol shows promising efficiency of 2.91%.
