Inhomogeneities in the optoelectronic properties of polycrystalline Cu(In,Ga)Se2 absorbers can limit solar cell performance. Now, researchers quantify the spatial distribution of charge carrier concentration with nanometre resolution and show how different alkali-metal post-deposition treatments reduce the grain-to-grain fluctuations.
