The Centre for Exciton Science will work on the development of new energy-efficient devices and energy storage structures such as solar cells, luminescent solar concentrators, and exciton up-conversion systems. The full application potential of emerging excitonic materials will be showcased and explored in prototype devices. We will work towards novel device designs that are compatible with low-cost fabrication techniques. The integration of the multitude of excitonic technologies developed in this Centre into integrated 3rd generation photovoltaics such as tandem solar cells and PV-integrated solar concentrators and upconverters will be a key focus. In addition, the Centre will explore novel spin-control devices and systematic optimisation of device parameters to facilitate translation and prototyping through partners such as CSIRO and Chinese partners.
