    • Disclosed herein are processes for making quaternary chalcogenide wafers. The process comprises heating a mixture of quaternary chalcogenide crystals and flux and then cooling the mixture to form a solidified mixture comprising ingots of quaternary chalcogenide and flux. The process also comprises isolating one or more ingots of quaternary chalcogenide from the solidified mixture and mounting at least one ingot in a polymer binder to form a quaternary chalcogenide-polymer composite. The process also comprises optionally slicing the quaternary chalcogenide-polymer composite to form one or more quaternary chalcogenide-polymer composite wafers. The quaternary chalcogenide wafers are useful for forming solar cells.
