Effect of TiO2 Thickness Dye Solar Cell on Charge Generation

A dye solar cell with a dimension of 6 x 2 cm is fabricated with thickness of 40 mu m, 80 mu m and 120 mu m of TiO2 by smearing it on an ITO coated glass. It is then tested under the average solar irradiance and temperature of 693.69 w/m2, 44.4 degrees C respectively. Based on experimental investigation it is found that TiO2 of 40 mu m produces V-oc = 0.21V, J(sc) = 121.28 mu A, while the 80 mu m produces V-oc = 0.16 V, I-sc = 69.89 mu A and TiO2 layer with thickness of 120 mu m produces Voc = 0.00063 V, I-sc = 0 mA. From these results it shows that the best charge generation is from the thinner TiO2 thickness layer which is the 40 mu m compare to with the other size.
