Project description

Key question: Can visible-light-response multiple exciton generation (VLR-MEG) be materialized in quantum dots (QDs) via metal ions doping to provide the potential to break the current conversion efficiency limit in solar energy?

Key result: We will develop QDs by doping strategies that can achieve a VLR-MEG, where absorption of a single photon with visible light leads to the excitation of multiple excitons. 

Key impact: The utilization of VLR-MEG QDs holds immense potential to surpass the theoretical limit of a single junction solar cell conversion efficiency improved to 44%. Furthermore, this technology could also pave the way for the accelerated development of photocatalytic conversion processes involving multi-electron processes such as CO2 reduction.
