Effect of TiO2 Thickness Dye Solar Cell on Charge Generation

AbstractA dye solar cell with a dimension of 6 × 2cm is fabricated with thickness of 40μm, 80μm and 120μm 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 oC respectively. Based on experimental investigation it is found that TiO2 of 40μm produces Voc = 0.21V, Jsc= 121.28μA, while the 80μm produces Voc= 0.16V, Isc= 69.89μA, and TiO2 layer with thickness of 120μm produces Voc = 0.00063V, Isc = 0mA. From these results it shows that the best charge generation is from the thinner TiO2 thickness layer which is the 40μm compare to with the other size
