PP2.2 Thin-Film Inorganic Cells

UNSW invented the thin-film silicon on glass (CSG) technology that holds the record efficiency worldwide of 10.5% for any thin-film silicon device (higher than any amorphous or microcrystalline device, despite the much larger developmental efforts with these technologies). Efficiency improvements are likely using laser annealing of related devices and the tandem approaches as outlined above, although reduced top cell quality is possible in this case. CZTS and related tandem cell structures are also of interest in their own right as thin-films and will also be investigated under this Program Package, in parallel with exploration of their epitaxial properties on silicon (PP1).
