Symposium EN03—Solar-Energy Conversion for Sustainable Water-Energy-Environmental Nexus
Adoption of renewable solar energy technologies are promising in addressing water-energy-environmental nexus, bringing on sustainable solutions of these inextricably linked scarce resources. Many of these emerging solar enabled technologies can boost water, energy and environmental security by improving sustainability, accessibility and affordability. Various advanced functional materials including plasmonic metal, semiconductor, carbon, hybrids etc. have been developed to effectively capture broad solar spectrum, whilst diversified solar energy conversion concepts associated to intermediate band, hot carrier, localized surface plasmon, up- and down-conversion, and multiple exciton generation are manipulated to efficiently harness solar energy. Moreover, prerequisites of efficient photo/photothermal driven processes include extended solar absorption, efficient optical-thermal management along with various strategies of rational nanostructure designs, bandgap engineering, material constituents tailoring and system configurations are judiciously considered. Recent deployment in solar evaporation, desalination, purification, sterilization and energy generation have shown promising clean water, energy and environmental solutions using less resource-intensive processes and technologies, compared to conventional options. The opportunities of renewable solar energy are explored beyond the silo, so as to address the key challenges posed by the interlinked water, energy and environmental nexus in mutually beneficial ways.
This symposium aims to bring together photo/photothermal communities with diverse disciplines to present and discuss recent advances in the solar powered sustainable water-energy technologies. Emphasis will place on solar materials, electrodes, membrane as well as device design and fabrication for solar catalysis, vaporization, desalination, purification/sterilization, solar induced pyro/thermo-electricity etc. This symposium highlights advanced nanomaterials exploration, theory-experiment verification and systematic protocol development. Researchers with different expertise attending this symposium will be exposed to cross-cutting discussion and network opportunities on emerging solar thermal and photon energy conversion technologies.
