Carrier concentration resolved

Inhomogeneities in the optoelectronic properties of polycrystalline Cu(In,Ga)Se 2 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 re...

Zusammenfassung:	Inhomogeneities in the optoelectronic properties of polycrystalline Cu(In,Ga)Se 2 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.
