The electrical properties of polycrystalline tin dioxide films were investigated by impedance spectroscopy in the frequency range 100 Hz-1 MHz at temperatures 4.2 K, 77 K and 300 K. Analysis of the experimental data by means of complex nonlinear least squares method made it possible to divide the contributions of grain bulk and grain boundaries to the conductivity. It was found that at room temperature charge transport processes are mainly determined by the grain volume while at the low temperatures contribution from the grain boundaries to the impedance of the system prevails.
