Photo-Electrocatalytic Applications of Pure and Bismuth Doped Zinc Oxide Thin Films by Spray Pyrolysis

Pure and bismuth doped zinc oxide thin films were grown by spray pyrolysis and they subjected to spectral and optical analysis. The surface morphology measurement of HR-SEM and HR-TEM images show nano flower shaped structure is observed by Bismuth. Zinc oxide thin films, the EDX analysis confirms that Zn, Bi and O present in thin films. XRD analysis reveals that as synthesized films polycrystalline wurtzite structure (Zincite), are and doped materials are present was done and average crystalline size (26 nm and 19 nm) was calculated by Scherer's formula. The PL analysis from doped thin film decreased intensity appear high efficiency was discussed. The optical study of UV-Vis DRS identify ZnO thin film increased band gab decreased from 3.32 eV to 3.20 eV and the efficiency increases from 5.6 mA/cm(2) to 7.00 mA/cm(2) respectively. And the doped thin films this result identifies decreased band gab energy high efficiency of catalytic and electrochemical application of (DSSCs) was done.
