TOWARDS HARVESTING MORE PHOTONS BY DEVELOPING NANOSTRUCTURED MATERIALS AND ASSERMBLIES

摘要

Efficiently harvesting visible and near infrared (NIR) photons represents an attractive approach to improve the efficiency of solar-to-electricity conversion, solar-to-fuel conversion and photocatalysis. Plasmonic nanostructures with unique surface plasmon resonance have recently been explored for enhancing solar energy harvesting in the visible and NIR regimes. On the other hand, NIR quantum dots (QDs) with size tunable bandgaps and high potential for multiple exciton generation represent a class of promising materials for new generations of solar cells. In this talk, I will present our recent work on the synthesis of plasmonic nanostructures, NIR QDs, and related assemblies as well as their applications in solar cells, solar fuel and photocatalysis.
