The symmetry-dependence of electronic grain boundary (GB) properties in polycrystalline CuInSe2 thin films was investigated in a combined study applying scanning electron microscopy, electron backscatter diffraction, and Kelvin probe force microscopy. We find that highly symmetric Sigma 3 GBs have a higher probability to be charge neutral than lower symmetric non-Sigma 3 GBs. This symmetry-dependence can help to explain the large variations of electronic properties found for GBs in Cu(In,Ga) Se-2. (C) 2011 American Institute of Physics. [doi:10.1063/1.3652915]
