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.
Solar cells were fabricated
from (Muscovite/ TiO2/Dye/Al), the effect of temperature, concen- tration
and light intensity on the electrical prop- erties of (Muscovite/TiO2/Dye/Al)
was studied. The relationship between current and voltage was found to be algorism,
which is in agreement with the ordinary relation for solar cells. When dye concentration
was increased the conductivity, fill factor and efficiency were also increased.
This result is found to be in conformity with the theoretical relations. The small
energy gaps for their samples show that they are semiconductors. The maximum efficiency
obtained is 33.2%.
