Sodium enhances indium-gallium interdiffusion in copper indium gallium diselenide photovoltaic absorbers

Sodium enhances indium-gallium interdiffusion in copper indium gallium diselenide photovoltaic absorbers

Sodium doping is necessary to achieve high performance in polycrystalline chalcopyrite solar cells, but retards gallium interdiffusion, and thus efficiency optimisation. Here, Colombara et al. show that in contrast to the polycrystalline case, sodium accelerates atomic interdiffusion in monocrystall...
