Microcrystalline based TiO2 thin film in dye-synthesized solar cell for efficient artificial photosynthesis

In today´s world Global warming possesses a serious threat to mankind and society. An increase in global temperature variations is uncertain. Artificial photosynthesis is a research field that attempts to replicate the natural process of photosynthesis, converting sunlight, water, and carbon-di-oxide into carbohydrates and oxygen. One of the approaches for artificial photosynthesis is by Dyesynthesized Solar Cell. It has three primary parts. On the top is a transparent anode made of fluorine-doped tin dioxide (SnO₂: F) deposited on the back of a (typically glass) plate. On the back of the conductive plate is a thin layer of titanium dioxide (TiO₂), which forms into a highly porous structure with an extremely high surface area. TiO₂ only absorbs a small fraction of the solar photons (those in the UV). It has some disadvantages such as the temperature stability is not good and secondly the lasting is not long. Hence we hypothize the use of microcrystalline TiO₂ thin film in the solar cell. The TiO₂ thin film can be fabricated using the sol gel process and the film is calcined after the process to increase the hardness. The TiO₂ film is deposited on an aluminum substrate. This film will be used inside the dye synthesized cell for better accuracy and long life. The simulation part is carried out using IntelliSuite software of Intellisense USA. Once the research behind artificial photosynthesis reaches a successful conclusion society will be able to truly reap the benefits of a steadily healing global climate. Looking forward to have a clean and green world.
