LOW MELTING POINT SPUTTER TARGETS FOR CHALCOGENIDE PHOTOVOLTAIC APPLICATIONS AND METHODS OF MANUFACTURING THE SAME

摘要

In one example embodiment, a sputter target structure for depositing semiconducting chalcogenide films is described. The sputter target includes a target body having a target body composition that comprises Cu1-x(Se1-y-zSyTez)x, wherein the value of x is greater than or equal to approximately 0.5, the value of y is between approximately 0 and approximately 1, the value of z is between approximately 0 and approximately 1, and the total amount of Se, S, and Te phases in the target body composition comprise less than 50 volume percent of the target body composition.
