In recent years perovskite solar cells have attracted an increasing scientific and technological interest in the scientific community. It is important to know that the temperature is one of the factors which have a strong effect on the efficiency of perovskite solar cell. This study communicates a temperature analysis on the photovoltaic parameters of CH₃NH₃PbI₃-based perovskite solar cell in a broad interval from 80 to 360 K. Strong temperature-dependent photovoltaic effects have been observed in the type of solar cell, which could be mainly attributed to CH₃NH₃PbI₃, showing a ferroelectric-paraelectric phase transition at low temperature (T < 160 K). An increase in temperature over the room temperature decreased the perovskite solar cell performance and reduced its efficiency from 16% to 9%. The investigation with electronic impedance spectroscopy reveals that at low temperature (T < 120 K) the charge transport layer limits the device performance, while at high temperature (T > 200 K), the interfacial charge recombination becomes the dominant factor.
