The meeting covers the latest developments in optics, photonics and advanced materials for the next generation of photovoltaic (PV) solar cells 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.
