Solar Energy and Light Emitting Devices (SOLED)

Solar Energy and Light-Emitting Devices

The meeting covers the latest developments in optics, photonics and advanced materials for the next generation of solar energy devices including photovoltaic (PV) solar cells and solar (thermal) collectors, and light-emitting diodes (LEDs). This includes all aspects of novel optical materials, nanostructures and devices; ranging from surface coatings, textures and diffraction gratings to topics such as plasmonics, nanowires, quantum dots for application in solar cells and LEDs - both conventional and emerging types alike. It also explores the range of optical elements for collecting, guiding, concentrating, coupling, trapping, transforming and absorbing sunlight – particularly for concentrating solar power (CSP). As optical components typically constitute the largest fraction of cost of such systems, the scope includes research devoted to improving all optical aspects of solar systems to enhance the performance, such as reducing levelized costs and maximizing long-term reliability.

Attendees will be presented with overarching topics such as the techno-economic analysis of the impact of optics on photovoltaic and solid-state lighting systems. The aim is to bring together solar energy researchers with LED researchers and connect them with the broader global optical research community to identify and promote synergies.

For the 2024 meeting, SOLED plans to organize a symposium on Radiative Cooling together with the Novel Optical Materials and Applications (NOMA) meeting.
