摘要
Organometal halide perovskites have been much studied as an active material in a new generation of solar cell with high power conversion efficiency. The chemical reactions involved in their crystallization process are simple but the crystallization process and the formed crystal are very sensitive to temperature and humidity. In general, if the electronic structure of this active material is easily affected by temperature, the working performance of its solar cell will be also easily affected by temperature. In this work, we investigated the temperature effect on the working performance, namely the J-V characteristics, of CH3NH3PbI3 perovskite based solar cell. The measurement result show that the J-V characteristic significantly changed with temperature. The J-V curve shows a diode characteristic at room temperature but it changes to an Ohmic characteristic at high temperature. This characteristics change may be due to the degradation of the perovskite crystals, which may be caused by separation and recrystallization PbI2 inside the perovskite layer.
