Abstract

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%.
