Solar cell: Photochemical cells based on dye sensitization of titanium dioxide and with indium tin oxide as
a conductor

T
he dye sensitized solar cell (DSSC) is a new type of solar cell which converts the visible light into electricity, by using indium tin
oxide (ITO) and photo electrochemical system. A photo electrochemical solar cell that is based on the dye sensitization of thin
microcrystalline films of titanium dioxide (TiO
2
) nanoparticles in touch with a liquid electrolyte solution is tested. The main task of
the project is to build a photochemical dye sensitized solar cell based on materials that are inexpensive and highly efficient in solar
energy conversion by using ITO and TiO
2
. The building process of the cell was started with the two conductive glass plate coated
with ITO. However, a thin layer of Titanium dioxide TiO
2
is applied on the conductive side of one glass plate and the other side of the
conductive glass plate is coated with graphite. A number of dyes such as natural strawberry and blue berries has been tested and then
applied on the thin layer of TiO
2
and then the two conductive glass plates are stacked together to be a complete cell. A few drops of
electrolyte solution such as pure iodine crystal, potassium iodide as well as ethylene glycol been added between the two conductive
glass plates, a thin layer of titanium dioxide and a layer of graphite. The operational principle of the cell has been recorded through the
measurement of the cell by emitting all wavelengths in the visible spectrum propagating from sunlight and exhibited steady voltage
and current at much higher level for approximately 230 mv for the cell dimension 2.5 cm x 2.5 cm. During the testing cell we have got
a problem with the nature of the electrolyte solution can undergo evaporation, leaking, charge separation at the titanium dioxide. For
this kind of cells we recommend to use filters to decrease the amount of heat reaching the cell. However, recommendations for the
future to improve the cell are made with using quantum dots. Quantum dots have the advantages of providing tunable band gaps and
the ability to absorb specific wavelength from the solar spectrum.
