Drift‐diffusion modeling is used to quantify different loss mechanisms in polymer:fullerene photovoltaic devices. Based on the modeling, which takes into account the carrier‐density dependence of the mobility, the relative importance of geminate recombination, bimolecular recombination, and the space‐charge effect are able to be quantified under different conditions.
