Is negative capacitance a hysteresis in the current–voltage curve?

Observable for a variety of devices, it is a rather universal phenomenon related to the hysteresis in the current–voltage curve. The apparent negative capacitance remains elusive in the impedance analysis of metal halide perovskite solar cells.

What is negative capacitance in perovskite solar cells?

Nature Communications 10, Article number: 1574 (2019) Cite this article So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells.

Why do perovskite solar cells have a high capacitance?

In conclusion, we have shown that high (positive and negative) apparent capacitances for low frequencies in perovskite solar cells are not due to a classical capacitive effect but due to slow transients in the injection current.
