Titanium dioxide is widely studied due to its interesting properties such as wide band gap, crystalline nature, low cost, high refractive index and environment friendly. Titanium dioxide nanoparticles are suitable for many applications such as solar cells (anode material in solar cell), in batteries and also in antireflection coating. It affects the efficiency of solar cell & capacity in Li ion battery. In the present work we discussed third-generation solar cells which are designed to achieve high power-conversion efficiency while being low-cost to produce. This review focuses on different types of third-generation solar cells such as dye-sensitized solar cells, Perovskite-based cells, and quantum dot solar cells. In these solar cells the TiO2is used as a photo anode due to its wide band gap, high refractive index and environment friendly nature. When TiO2 is used as photo anode in DSSC then, its efficiency is increased up to 8.02%. Similarly, if TiO2 is used as photo anode in QDSSC, its efficiency is increased up to 13.84%.TiO2 used as an electron transport layer (ETL) in PSC, its efficiency reaches 13%.This also includes working principles and components of third generation solar cells. For Li-ion battery,TiO2 has been used as an anode material due to its high structural stability, stable capacity and fast charge ability for lithium-ion insertion and desertion. This anode material avoids short circuit and battery explosion problem and also reduced the cost. TiO2 enhances the performance of the third generation solar cells and Li-ion battery. Another application of TiO2 is that it is used as an antireflective coating. TiO2 as an antireflective coating reduces reflection and enhance light absorption.
