Abstract

Model to represent the behaviour of photovoltaic (PV) solar cells in reverse bias is reviewed, concluding with a proposal of new model. This model comes from the study of avalanche mechanisms in PV solar cells, it can be adapted to PV cells witch reverse characteristic is dominated by avalanche mechanisms, and also dominated by shunt resistance. A simulation of shading effects in arrays with parallel series configuration has been done; an analysis has been made of the power dissipation with the influence of the number of shaded cells and the effect of shadowing degree.
