Abstract

The parameter J₀, commonly used in solar cell modelling, has a deep physical meaning, which this paper intends to clarify. Upon examination, J₀ can be identified as the recombination current density in thermal equilibrium. In many cases the same equilibrium parameter J0 can be used to describe carrier recombination under external illumination. Nevertheless, when carriers flow from the point where they are generated towards a high recombination site the value of J₀ that matters to solar cell operation differs from that in equilibrium. In addition, J₀ may in certain cases be dependent on the excess carrier concentration. We conclude by recommending that J₀ be referred to as a recombination parameter.
