Abstract
Optoelectronic devices having enhanced conversion efficiencies and associated methods are provided. In one aspect, for example, a method of making an optoelectronic device can include applying an absorption layer onto a support substrate, the absorption layer including a material such as CIGS, CIG, CI, CZT, CdTe, and combinations thereof. Additional steps include providing a element-rich environment in proximity to the absorption layer, and irradiating at least a portion of the absorption layer with laser radiation through the element-rich environment thereby incorporating the element into the absorption layer.
