Abstract
Modifying the wavelengths of sunlight via luminescent materials – so-called spectral conversion – can take several forms. Up-conversion materials (UC) materials can be used to harvest sub-bandgap photons on the rear side of silicon solar cells. Down-conversion (DC) layers offer the promise of being able to emit two lower energy photon for each higher energy photon, thus potentially enabling a step-change in silicon PV device performance. Finally, luminescent down-shifting (LDS) layers offer the potential of overcoming short-wavelength external quantum efficiency losses as well as enhancing the photostability of both silicon and perovskite solar cells. Finally, harvesting sunlight for other purposes – such as plant growth in greenhouses – will also be examined.

Brief Bio
Bryce studied physics at the Victoria Univ. of Wellington (New Zealand) before completing a Masters and PhD in electrical engineering at Univ. of New South Wales (Australia),
in 1998 and 2002, respectively. He worked as a postdoc at both UNSW and the Australian National University. In 2006, he left Australia and joined Heriot-Watt University (Edinburgh, U.K.) as a lecturer, being promoted to full professor in 2008. Since 2014 he is co-director of the Institute for Microstructure Technology (IMT) and Light Technology Institute (LTI) within the Karlsruhe Institute of Technology (Germany). His primary research areas lie in the synthesis and application of spectral conversion materials (up- and down-conversion and luminescent down-shifting) to photovoltaics, as well as more recently also exploring the applications of luminescent materials for i) boosting plant growth in next generation greenhouses; ii) biological imaging and iii) plastic
recycling.
