            As an alternative to inorganic III-V materials, chalcogenide semiconductors are another group of promising photovoltaic materials for silicon-based tandems with high efficiency potential, low-cost potential, and demonstrated long term stability.

This work package will progress the development of metal chalcogenides to target >20% efficiency semitransparent high bandgap chalcogenide cells, and 30% efficiency chalcogenide/silicon tandem cells, using manufacturing sequences compatible with silicon production lines and through the direct growth of top cell and alternative cost-effective tri-chloro-acetic (TCA) bonding technologies.
