Models to represent the behaviour of photovoltaic (PV) solar cells in reverse bias are reviewed, concluding with the proposal of a new model. This model comes from the study of avalanche mechanisms in PV solar cells, and counts on physically meaningful parameters.
In practice, the reverse-bias issue is encountered in solar modules under partial shading, where the shaded cell is forced into reverse bias in an attempt to pass the photocurrent of its unshaded and series-connected neighbors.

A second, more common approach, is to stabilize solar cells under high reverse bias, typically by improving breakdown voltage (Vrb) and thus minimizing the number of bypass diodes needed to protect a solar panel 29. This approach, widely seen in commercial silicon PV 30, 31, is studied more often for perovskite PV at present 16, 17, 21.
