Solution based process of ZnO nanostructured thin films: A review

Abstract The solution-based technique is recently gaining momentum for the fabrication of optoelectronic materials due to its cost-effectiveness, fabrication of large-scale thin films, processing at low temperature, low cost and simplicity of the process requirements. The properties of thin films depend on the diverse parameters like substrate, deposition time, source materials, doping agent, pH and temperature at which the process is done. ZnO nanostructured thin film has been widely used in organic and hybrid solar cells due to its precise characters such as reduced cost, simple processing, non-toxicity, better optoelectronic properties and good stability. In this review article, we have focused on different solution-based methods which are capable of yielding good quality thin films of ZnO with different morphology for various applications.
