This study reveals that analyzing capacitance transients in perovskite solar cells is more complex than previously thought. It demonstrates that the direction of these transients is influenced by the cell's layer dominating capacitance modulation, not by the polarity of migrating species. This highlights the significant role of transport layers in characterizing mobile ions in perovskites.

Setfos was used

To investigate the role of the polarity of mobile ions in capacitance measurements the researchers simulated the behavior of the capacitance as a function of time after a voltage pulse. The Drift-Diffusion module in Setfos was used to simulate the capacitance transients.
