Atomic-scale distribution of impurities in CuInSe2-based thin-film solar cells

Atom Probe Tomography was employed to investigate the distribution of impurities, in particular sodium and oxygen, in a CuInSe(2)-based thin-film solar cell. It could be shown that sodium, oxygen, and silicon diffuse from the soda lime glass substrate into the CuInSe(2) film and accumulate at the gr...
