MRS Spring Meeting 2019 – Excitonic Materials & Quantum Dots for Energy Conversion

31 Jan 2019

Symposium ES19 – Excitonic Materials and Quantum Dots for Energy Conversion

Multi-excitonic processes in conjugated organic molecules and quantum confined semiconductor nanocrystals potentially allow the energy in photons to be directed as desired. Design of the molecular framework or material nanostructure will allow a wide range of optical, electronic and mechanical properties to be engineered for energy conversion. This symposium will emphasize the diverse applications of excitonic materials, including colloidally synthesized quantum dots, pi-conjugated systems, and their hybrid constituents, in applications ranging from photovoltaics to bioimaging. There will also be sessions focusing on fundamental materials properties correlating structure to photophysical properties, nano- and mesoscale order and composition to optoelectronic properties of thin films. The symposium will highlight recent progress and identify new directions in emerging, interdisciplinary areas of nanoscience.

Nanoscale Advances is delighted to sponsor this session.

Topics will include:

Computational methods for excitonic materials
Exciton-based photon upconversion
Multiple exciton generation in QDs
Singlet fission in molecules or polymers
Exciton-charge dynamics in organic/QD hybrid systems
Optoelectronic devices (e.g. transistors, photodetectors) based on exciton or charge transport
Role of the interface in energy and charge transport
Hierarchical order at the nano- and mesoscale (e.g. organic or QD thin films)
Emerging applications incorporating colloidally-synthesized QDs, e.g. Biological: in-vivo and in-vitro; Photocatalysis: solar fuel production; Next-generation photovoltaics with the lead chalcogenides and perovskites
