Abstract A better understanding of the open-circuit voltage () related losses in organic solar cells (OSCs) is desirable in order to assess their photovoltaic performance. We have derived as a function of charge carrier mobilities (and) for organic and hybrid solar cells by optimizing the drift-diffusion current density. The thus obtained depends on the energy difference between the highest occupied molecular orbital (HOMO) level and the quasi-Fermi level of holes of the donor material and on the ratio of the electron () and hole () mobilities in the blend. It is found that the increases with the increase of the mobility ratio. The most loss in is contributed by the energetics of the donor and acceptor materials.
