Impact of the light intensity variation on the performance of solar cell constructed from (Muscovite/TiO 2 /Dye/Al)

In this work, the influence of the light intensity as one of the parameters that control the solar cell is studied. The effect of the other main variables, such as temperature, rotation per Minuit of the spin coating instrument, and the samples concentration, was found to be in conformity with other results, but unfortunately the intensity of light does not increase the solar cell efficiency, and fill factor, by other words it was found to play only a secondary role.
