- This experimental work resulting from a collaboration between SHU and UoSheffield validated bandgap first-principles calculations (Phys. Rev. B, 2014, 89, 235105) performed by Prof. Rappe from UPennsylvania on potentially new photovoltaic materials, which may allow power conversion efficiencies beyond the Schockley-Queisser limit. In addition, this study also unveiled for the first time an evolution towards a non-ferroelectric state, which was not captured by previous theoretical work. Part of this research was funded through EPSRC grant (EP/L017563/1, Substitution and Sustainability in Functional Materials and Devices) and a VC scholarship from SHU.
