​3.1.1 High Efficiency, Stable, Wide and Narrow Bandgap Perovskite Cells

• Demonstrate progress in high performance wide and narrow bandgap perovskite cells.

• Demonstrate progress in high voltage high bandgap cells with minimum halide segregation.

• Minimize non-radiative recombination and reduce voltage losses using perovskite compositional engineering, additive engineering, interfacial engineering and device engineering.

• Developing and investigating novel defect passivation strategies guided by sophisticated modelling and characterization techniques, including the accurate quantification of the relative contributions from bulk and surface defects.
