Synthesis of nano-TiO2 assisted by diethylene glycol for use in high efficiency dye-sensitized solar cells

The TiO2-diethylene glycol (DEG) based dye-sensitized solar cells perform a noticeable improvement in the overall efficiency of maximum 7.90% which is higher than 7.53% for the cell made of TiO2 (DEG free) and 6.59% for the cell made of P25.
