This paper describes the TiO2 performance based energy gap related to its annealing process. TiO2 is one of the comprehensive band gap semiconductor materials which has been under extensive investigation in recently. This is due to its application in various fields such as photo electrolysis, photo catalysis, dye sensitized solar cells, gas sensor, optical fibers etc. Furthermore, advent of nanotechnology increases its applications many fold and different types of TiO2 have been used for different types of sensing applications. The TiO2 exists in different crystalline forms such as anatase, rutile and brookite. Solar cells consists of mono-crystalline, thin films, dye sensitized solar cells and multi-junction. TiO2 can be produced by using techniques like sputtering, vacuum evaporation, pulse laser deposition, molecular beam epitaxial, sol-gel and chemical bath deposition. Successful annealing process leads to a high performance solar cells. To fabricate the solar cells, there are four types of ways which are doctor blading, spin coat, sol-gel and screen printing. A comparison of annealing process, nanoscale structure and performance output powers been done successfully. The produced TiO2 also been tested with a high power performance.

Pure anatase TiO2 spheres with mesoporous structure were prepared by a simple urea assisted hydrothermal process at low temperature. X-ray Diffractometer, Scanning Electron Microscope, Transmission Electron Microscope, and N2 adsorption-desorption were used to characterize TiO2 . The dye-sensitized solar cells results show that an overall light conversion efficiency of 6.96% which is 36.7% higher than that of the overall efficiency (5.09%) obtained from the P25 photoanode owing to the superior light scattering effect and the high level of dye loading capacity of microspheres.
