The fabrication of zinc oxide(ZnO) from inexpensive solution-processing techniques,namely,electrochemical deposition and electrospinning were explored on various conducting and mesoporous semiconducting surfaces.Optimised conditions were derived for template- and self-assisted nano/micro structures and composites. ZnO thin films were annealed at a fixed temperature under ambient conditions and characterised using physical and optical techniques.The photocurrent response in the UV region shows a fast rise and double decay behaviour with a fast component followed by a slow oscillatory decay.Photocurrent results were correlated with surface chemical analysis from X-ray photoelectron spectroscopy.Various characterisation details reveal the importance of fabrication parameter optimisation for useful low-cost optoelectronic applications.
