It is the crying need of the day to search out alternative source of energy to meet the national as well as international energy crisis. As the conventional sources of energy are being exhausted at a faster rate, so the world has been facing energy crisis. To meet this crisis we have to use nonconventional source of energy such as (i) nuclear energy (ii) wind energy (iii) solar energy (iv) Biomass energy and so on, Out of these various sources, it is very easy, convenient and inexpensive to harness the solar energy which is ample in amount and non exhausting, so our aim is to transfer this solar energy into electrical energy with the help of solar cells. Among various solar energy, converter the wet solar cell which is photo Electrochemical solar cell due to low cost and ease of fabrication in mass production and having good power conversion efficiency and also pollution free depending on low energy band gap electrode. The graph for better semiconducting material for PEC solar cell lies in the fact that low band gap material corrodes in electrolyte. Several investigator have fabricated PEC solar cells using tungsten trioxide, dioxide, monoxide, tin mono sulphide, cadmium telluride and so on. But it is seen that transparent film of SnO2 having considerably large band gap as alternative for fabricating PEC solar cell as it is non-corrosive in nature. It is obtained that tin oxide material as an electrode and selecting SnCl4 as its electrolyte, PEC solar cell can be fabricated to give better power conversion efficiency with considerable amount. The whole world is going ahead to harness the solar energy into different uses such as defence, industries and in research laboratories via photo electro chemical solar cell.
