Understanding the Optical, Electrical and Photoelectrochemical Properties of PbTiO3 Thin Films

PbTiO3 thin films were synthesized using spin coating sol gel method and sintered at three different temperatures. All the thin films sample were analysed using XRD, scanning electron microscopy, Raman spectroscopy, UV-Vis spectroscopy analysis which shows that PbTiO3 films were having cubic crystal structure with band gap value of 3.0 eV respectively. The photoelectrochemical response was also observed in three electrode PEC cell. Photoanodic behaviour for PbTiO3 films with highest photocurrent density of 1.2 mAcm−2 at 0.8 V/Ag/AgCl for sample sintered at 650 °C was observed.
