The DSSC devices containing these TiOPc derivatives exhibited short-circuit current densities of 8.49~10.04 mA/cm2 and power conversion efficiencies of 2.73~3.62 % under AM 1.5 illumination and 100 mW/cm2 irradiation. Keywords: Titanyl phthalocyanine (TiOPc); Dye-sensitized solar cell; Polymer electrolyte. 1. Introduction Dye-sensitized solar cells (DSSCs) constructed using dye molecules, nanocrystalline metal
