Vapour-deposited wide-bandgap semiconductors for photovoltaic and thermoelectric applications

Thesis

Realising the efficiency potential of multi-junction perovskite solar cells requires semiconductors with bandgaps near 2 eV. To date, however, research has been dominated by materials optimised for single-junction or silicon-perovskite tandem architectures requiring narrower bandgaps, leaving the wide-bandgap space comparatively underexplored. Halide-based compounds represent a compelling class of candidates, offering tuneable optical properties through compositional control, strong optica...
