The influence of the choice of temperature, pH value, counter‐ion, deposition time, and seed layer on the morphology as well as electrical properties of ZnO films grown from chemical bath deposition (CBD) are discussed. Consequently, oriented ZnO films with various microstructures can be synthesized by controlling the solution pH value and counter‐ions. Besides, the point at which the seed layer is pre‐heated at higher temperature is crucial and can lead to a significant difference in the width of crystals and electrical properties of ZnO films.
