Abstract
In one embodiment, a method includes depositing a CIGS precursor layer onto a substrate, introducing a source-material layer into proximity with the precursor layer, where the source-material layer includes one or more of Cu, In, or Ga, and one or more of S or Se, and annealing the precursor layer in proximity with of the source-material layer, where the annealing is performed in a constrained volume, and where the presence of the source-material layer reduces decomposition of volatile species from the precursor layer during annealing.
