Abstract
We have studied the influence of annealing temperatures on the crystal structure, surface morphology, optical and photoelectrochemical (PEC) properties of CdSe nanofiber film electrodes synthesized by electrodeposition technique. The crystal structure and surface morphology of CdSe film electrodes were examined using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques, respectively. The optical absorption study of as-synthesized and annealed CdSe films on tin-doped indium oxide (ITO) substrates were measured by spectrophotometer. As-synthesized amorphous/nanocrystalline CdSe film electrodes were changed to crystalline after annealing at 473 K for 1 h, where the improved photoelectrochemical performance conversion efficiency of 2.01% was obtained.
