annealing process gives rise to a significant increase in the short current density and the photoconversion efficiency. Interesting results were obtained in TiO2 based solar cell sensitized by 1(4),8(11),15(18),22(25)-tetra-([2-phenyl]phenoxy)phthalocyaninatocopper under optimized conditions. The DSSC devices containing this compound exhibited short-circuit current densities of 12.2 mA cm−2 and solar energy-to-electricity
