The Effect of Doping Concentration on the Performance of Solar Cell constructed from (Muscovite/TiO2/Dye/Al)

Abstract

Solar cells were fabricated from (Muscovite /TiO2/Dye/Al), the effect of temperature, concentration and light intensity on the electrical properties of (Muscovite /TiO2/Dye/Al) was studied. The relationship between current and voltage was found to be algorism. When dye concentration was increased the conductivity, fill factor and efficiency increased. Also, for these samples it was found that the open circuit voltage, fill factor and efficiency decreased with increased temperature and light intensity. Also, the energy gap was calculated and found to be 2.3 eV.
