Improved Sequentially Processed Cu(In,Ga)(S,Se)<sub>2</sub> by Ag Alloying
Abstract
<jats:p>Alloying small quantities of silver into Cu(In,Ga)Se<jats:sub>2</jats:sub> is shown to improve the efficiency for wide and low bandgap solar cells. Low bandgap industrial Cu(In,Ga)(S,Se)<jats:sub>2</jats:sub> absorbers are studied, substituting less than 10% of the copper with silver, using absolute photoluminescence and cathodoluminescence spectroscopy. Silver improves the grain size and promotes the interdiffusion of Ga and In across the depth of the absorber, resulting in a smoother bandgap gradient. However, a certain lateral inhomogeneity is observed near the front and back sides. The nonradiative losses in the bare absorbers are reduced by up to 30 meV.</jats:p>
