Yes, it is possible to add a metal as a doping materials with low concentrations to titanium dioxide to enhance the performance of the solar cell. Many works have been published is this regards
Dear Dr. Maytham Qabel Hamzah, there are recent reports concerning about the application of titanium dioxide nanomaterials in photovoltaic devices, including dye-sensitized solar cells. For the detailed review, please have a look in to the attached review document. I hope it will give you sufficient information.

Indeed, it is possible to add titanium dioxide to heighten the performance of solar cells. Many recent works have elaborated on this (@Dr. Beemnet). Its aggregate in dye-sensitized solar cells have a lot of benefits. It aids in reducing the cost of solar cells (comparison with silicon solar cells). Also, it has high dielectric constant, humidity and oxygen sensitivities. It also has very good magnetic, mechanical and optical qualities.
