Sodium Induced Beneficial Effects in Wide Bandgap Cu(In,Ga)S2 Solar Cell With 15.7% Efficiency

Progress in Photovoltaics: Research and Applications, EarlyView.
Wide bandgap Cu(In,Ga)S2 absorbers grown on soda‐lime glass (SLG) were optimized by introducing additional sodium (Na) via in situ NaF co‐evaporation. Optimal Na incorporation enhanced crystallinity, minimized Ga fluctuations across the depth, suppressed bulk defects, and reduced non‐radiative losses.
