[16p-P6-30] Possible Origin of IV-Curve Hysteresis in Perovskite Solar Cells

Keywords:perovskite solar cell, hysteresis, ferroelectric

Possible origin of IV-curve hysteresis in perovskite solar cells is presented by considering the fundamental aspect of solar cell operation as well as the ferroelectric nature of perovskite materials, which may induce the band fluctuation that intensively decreases the current flow with increasing output voltage.
