Abstract: We develop an analytical model for the photocurrent of organic solar cells based on carrier drift and including second-order charge recombination, in which the figure of merit ?o naturally appears. This approach provides expressions for the fill-factor- ?o and a-?o relations, where a is the exponent of the function of the short-circuit current versus light intensity (JSC ??Ia). A correlation between the reduction factor of Langevin recombination and the dissociation probability of charge transfer states (P) is also discussed. Photocurrent curves of a polymer device obtained at different temperatures (100-300 K) are fitted by the model, whose fitting parameters are in agreement with the literature.
