A dynamic electrical model (DEM) is introduced to describe perovskite based solar cells.
- class="label">•
The DEM reproduces hysteretic effects in the I-V characteristics observed experimentally.
- class="label">•
The current overshoot in reverse is correlated with the solar cell pre-conditioning.
- class="label">•
The dynamic hysteresis is analyzed with respect to changing the bias scan rate.
- class="label">•
The DEM is a practical tool for future calibration of tentative microscopic descriptions.
