The Dye Sensitized Solar Cell (DSSC)plays an important role because of low material cost, ease of
production and high conversion efficiency as compared to other thin-film solar cell technologies.
The main objective is to create and find the best configuration of the solar cell based on materials
that are inexpensive and highly efficient in solar energy conversion and subsequently test the efficiency
of dye sensitized titanium dioxide solar cell. We begin the process with two glass plates
coated with Fluorine tin oxide (FTO). Titanium dioxide is applied to the conductive side of one
plate and the other plate is coated with graphite. A dye is adsorbed on to the TiOzlayer and then
the plates are sandwiched together. Adrop of iodide electrolyte is then added between the plates.
The tests carried out indoors under a lamp emitting all wavelengths in the visible spectrum were
not found to provide consistent data due to substantial heating of the cell. The outdoor tests carried
out in natural sunlight exhibited steady voltage at much higher level. Future research will involve
the incorporation of quantum dots instead of the organic dye as a sensitizer. Quantum dots
have the advantages of providing tunable band gaps and the ability to absorb specific wavelength.
