Abstract: A general problem arising in computer simulations is the number of materialand device parameters, which have to be determined by dedicated experiments andsimulation-based parameter extraction. In this study we analyze measurements ofthe short-circuit current dependence on the active layer thickness andcurrent-voltage curves in poly3-hexylthiophene:6,6-phenyl-C61-butyric acidmethyl ester P3HT:PCBM based solar cells. We have identified a set ofparameter values including dissociation parameters that describe theexperimental data. The overall agreement of our model with experiment is good,however a discrepancy in the thickness dependence of the current-voltage curvequestions the influence of the electric field in the dissociation process. Inaddition transient simulations are analyzed which show that a measurement ofthe turn-off photocurrent can be useful for estimating charge carriermobilities.
