摘要: Based on simple analytical equations, short circuit current density (JSC) of the organic bulk heterojunction solar cells has been calculated. It is found that the optical interference effect plays a very important role in the determination of JSC; and obvious oscillatory behaviour of JSC was observed as a function of thickness. At the same time, the influence of the carrier lifetime on JSC also cannot be neglected. When the carrier lifetime is relatively short, JSC only increases at the initial stage and then decreases rapidly with the increase of active layer thickness. However, for a relatively long carrier lifetime, the exciton dissociation probability must be considered, and JSC behaves wave-like with the increase of active layer thickness. The validity of this model is confirmed by the experimental results.
