    The electrophysical characteristics comparative studies were carried out for ZnO films obtained by chemical precipitation from zinc acetate solutions and thermal oxidation of zinc films. The ZnO films showed optical absorption and band gap (2.9 to 3.2 eV) specific for this material, which indicates the presence of crystalline structure in them. The use of polyvinyl alcohol made it possible to obtain samples with the highest values of E g and electrical resistance, which is caused by the nanosize crystallites of the films. The investigated electrophysical characteristics of the ZnO films made it possible to establish the contribution of their own defects and surface states to the conductivity.
