Abstract: The present invention is a thick film silver composition for use a solar cell device. The thick film paste composition comprises an electrically conductive silver powder, one or more glass frits, a nano-sized additive wherein the nano-sized additive is selected from metallic zinc, zinc alloys or a mixture of metallic zinc and zinc oxide, all dispersed in an organic medium.

Abstract: The present invention relates to screen-printable quaternary chalcogenide compositions. The present invention also provides a process for creating an essentially pure crystalline layer of the quaternary chalcogenide on a substrate. Such coated substrates contain p-type semiconductors and are useful as the absorber layer in a solar cell.

Abstract: 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.
