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.
What are the different types of reverse characteristics in PV solar cells?
It can also be applied to the different types of reverse characteristics found in PV solar cells: those dominated by avalanche mechanisms, and also those in which avalanche is not perceived because they are dominated by shunt resistance or because breakdown takes place out of a safe measurement range.
