Abstract

Dye Sensitized Solar cells (DSSC) using Z907 Ru-dye were fabricated with different thickness of the TiO2 dense layer. The optical, photovoltaic and structural properties of the DSSCs with the different thickness of dense layers are studied and compared. The experimental results show that the DSSC with TiO2 layer thickness of 50 μm gives efficiency of 6.59%, the DSSCs with TiO2 layer thickness of 100nm provides an efficiency of 1.35%. The IV characteristics were measured under solar radiation intensity of about 100W/cm2. The DSSCs fabricated with TiO2 layer thickness of 150 nm were showing short circuit. The DSSC with 50 nm TiO2 layer transmit 80% of light to active layer while devices with 100 nm thick TiO2 layer transmit less than 50 % of incident light..
