As a suitable recombination process, recombination via tail state in organic bulk-heterojunction solar cells (OBHJs) is capable of reproducing both dark and illuminated current–voltage curves. The characteristic parameters of OBHJs based on recombination via tail are governed by transportation and extraction efficiency, and both processes are strongly dependent on the charge carrier mobility. Using a macroscopic simulation, we calculate the mobility dependent power conversion efficiency, open-circuit voltage, short-circuit current and fill factor. The open-circuit voltage is determined by not only carrier density n(p), but also by carrier density gradient. Furthermore, open-circuit voltage is more affected by majority charge carriers and less affected by minority ones.
