Abstract
The synthetic dye sensitizer based solar cells were successfully fabricated and photovoltaic performance was measured. Titanium dioxide (TiO2) nanoparticles were synthesized using sol–gel technique. The XRD and HRTEM analysis were carried out to determine the structural and morphological property of TiO2 nanoparticles. The crystalline sizes of the TiO2 particles were determined by XRD and were confirmed by TEM. The synthetic Coomassie Brilliant Blue (CBB) dissolved in acetonitrile was used as a dye in the nanocrystalline Tio2 solar cell. TiO2 films on FTO glass substrate were prepared by simple doctor blade technique. The dye was characterized by UV-Vis absorption spectroscopic analysis. The strong absorption of the CBB dye enhanced the DSSC property. The results showed that TiO2 as photoanode and CBB as a sensitizers showed good conversion efficiency
