Summary The major objectives of this subcontract were to explore, prepare, and test the candidate II-VI materials for top cells in two-junction devices with either monolithic two-terminal or mechanically stacked four-terminal structures. We developed two candidate alloys, CdMnTe, and CdMgTe by RF sputtering. The critical chloride treatments and related material studies revealed that CdMgTe is superior to CdMnTe. In the second year of this project, much of the effort was to develop the CdMgTe alloy. The goal of these efforts was to optimize the film deposition conditions and chloride treatments, and to identify the efficiency-limiting factors in a single-junction CdTe/CdS device that can lead to the goal of 25%-efficient tandem structures fabricated using polycrystalline thin films. The present report is the final report covering all three Phases.
