Optics in Solar Energy (SOLAR)

Optics in Solar Energy (SOLAR)

05 - 08 November 2018
Resort World Sentosa, Sentosa Island, Singapore

The meeting covers the latest developments in nanophotonics, advanced silicon wafer solar cells and advanced materials for the next generation of solar cells. This includes all aspects of novel materials, structures and optical nanostructures, ranging from surface coatings, textures and diffraction gratings through to emerging topics such as plasmonics, nanowires, quantum dots, multi-junction solar cells and perovskites, amongst many others.

It also explores the range of optical elements for collecting, guiding, concentrating, coupling, trapping, transforming and absorbing sunlight – particularly for solar-thermal and concentrator systems. 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, reduce costs and maximize reliability.

Attendees will be presented with overarching topics such as the techno-economic analysis of optics for solar energy, as well as optics in solar forecasting, atmospheric research and measurement, laser-based diagnostics of reactive solar-thermal flows and other fields. The aim is to bring together solar energy researchers with the broader global optical research community to identify and promote such synergies.

For 2018, this meeting merges Optical Nanostructures and Advanced Materials for Photovoltaics (PV) and Optics for Solar Energy (SOLAR).

Plenary Session

Photovoltaics Moving into the Terawatt Age

In the last few years, PV electricity became cost-competitive with electricity produced by conventional sources. Global PV production capacity will reach in the next 2-3 years 100-120 GWp/a, doubling the production volume of 2016, soon bringing global PV installations into the Terawatt range. A key factor for this growth will be continuous technology advances aimed at higher efficiencies at reduced cost. In addition, cell efficiency will be even more important than lowest cost, to optimize energy harvest from a given area. Crystalline Silicon technology currently represents more than 90% of the global PV market. This technology is approaching a ceiling of 29% efficiency for a single-bandgap semiconductor. New approaches for higher efficiencies require heterojunctions, and several approaches will be discussed. These include heterojunctions on silicon, allowing to combine well-established large-scale Silicon PV technology with new technologies, such as low-cost III/V or Perovskite layers.
