Abstract:
In this work, the effect of temperature on photoconductivity and its spectral dependence for thin films of metal-organic perovskite CH$_{3}$NH$_{3}$PbI$_{3}$ was studied. Measurements carried out in the temperature region below room temperature revealed specific features of photoconductivity variation with temperature in the phase transition region from the tetragonal to orthorhombic structure (140–170 K). Based on the analysis of the effect of temperature on the spectral dependences of photoconductivity in the region of the phase transition mechanisms are proposed that determine the observed change in photoconductivity
Keywords:
