The up-scaling of indium-tin-oxide-free (ITO-free) solar cells from 1 to 6 cm in length and the effect of grid line resistance are explored for a series of devices. Theoretical modeling enables the identification of the most rational cell dimensions and illustrates the electric potential field in the devices. Performance of the ITO-free organic solar cells with different dimensions and different electrode resistances are evaluated for different light intensities.
