Fourier Transform Spectroscopy (FTS)

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

Today, Fourier transform spectrometers onboard satellites looking downwards provide new insights on the Earth's atmosphere, climate, and a host of other meteorological and remote sensing applications. Instruments looking out provide a wealth of data targeting galaxies, stars, planets, and many smaller objects within the universe. Ground-based FT interferometers explore a variety of astrophysical and terrestrial fields including the global geographic distribution of CO2 sources and sinks. Chip-scale interferometers fabricated using state-of-the-art nanotechnology open up new opportunities for space and industrial applications. Laser frequency combs dramatically improve the resolution and recording speed of Fourier spectrometers. New spectral regions (e.g., VUV or THz) are under exploration with synchrotron radiation. Ultrashort laser pulses expand the territory of FTS to nonlinear and multidimensional spectroscopy. This international conference will provide a unique opportunity to discuss many of these exciting developments in a strongly interdisciplinary environment.

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.
