We have synthesized soluble TiOPc derivatives containing alkoxy groups for use as additives in dye-sensitized solar cells (DSSCs). The DSSC devices containing these TiOPc derivatives exhibited short-circuit current densities of 8.49~10.04 mA/cm(2) and power conversion efficiencies of 2.73~3.62 % under AM 1.5 illumination and 100 mW/cm(2) irradiation.
