JSIII – Photonics for Renewable Energy and Sustainability
Co-chairs: 
Svetlana Boriskina, MIT, Boston, USA and Jan Goldschmidt, Fraunhofer ISE, Freiburg, Germany

Advances in optics and photonics play an outsized role in reshaping the landscape of the next-generation energy-harvesting, conversion and saving technologies. Nanostructured devices and materials offer a way to overcome the conventional light absorption limits. Novel optical spectrum splitting and photon-recycling schemes boost the efficiency of optical energy-conversion platforms. Furthermore, optical design concepts are rapidly expanding into the infrared energy band, offering new approaches to harvest waste heat and to reduce the thermal emission losses in solar-thermal and solar water desalination platforms. Broadband engineering of the emission properties of optical materials and devices also paves the way to achieving noncontact radiative cooling of solar cells, electronic circuitries, buildings, and vehicles. Light–matter interaction enabled by nanophotonics and plasmonics underlie the performance of the third- and fourth-generation energy-conversion devices, including up- and down-conversion of photon energy, near-field radiative energy transfer, and hot electron generation and harvesting. Miniaturization of the energy harvesting photonic devices combined with the recent effort in developing optical materials for fully passive thermal regulation via radiation holds the promise to revolutionize wearable technologies. Low-loss optical communication networks help to reduce the growing energy demands and environmental heating effects. This symposium will put in the spotlight these recent advances in photonics and their applications to traditional and emerging applications in energy generation and sustainability. It seeks contributions offering transformative ideas on photon harvesting, spectral sorting, up- and down-conversion, emission control, and new applications beyond conventional solar cell technologies.

JSIV – Nanoscale Heat Processes
Co-Chairs: Sebastian Volz, Tokyo University, Japan and Roberto Li Voti, University Rome, Italy

Heat is one of the main forms of energy and its control is of critical importance to efficiently manage the energy resources of nature and global warming issues. Nanoscale heat transfer and management is an extremely “hot” research topic, challenging due to the continuous miniaturization of devices, and in rapid development as proven by many scientific articles published in the best journals and magazines of physics, material science, optics and chemistry.

The purpose of the “Nanoscale heat process” Symposium is to discuss the state of the art in the Nanoscale Heat Transfer and management, as well as the recent advances in the study of self-heating via electron-phonon interaction in nano devices, and of near field radiation, allowing to exchange relevant information, to promote collaboration among scientists and to provide the scientific basis to the newcomers.

Participants are encouraged to present their own results in the field.
