Plasmonic Enhancement and Directionality of Emission for Advanced Luminescent Solar Devices (PEDAL)

Keywords: Plasmonic interaction; solar energy; metal nanoparticles; light matter interaction quantum dot; ray tracing model; polymer; solar cell; spectroscopy; chemical synthesis.

Buildings play a significant role in the global energy balance. Typically they account for 20-30% of the total primary energy requirement of industrialized countries, 40% in the EU. Applying photovoltaic (PV) panels to buildings is an important application for wider PV deployment and to achieving our 20% Renewable Energy EU target by 2020. In Europe about 50% of the solar radiation is diffuse.

PEDAL will concentrate both direct and diffuse solar radiation in a static building component delivering not only breakthroughs in solar device efficiencies but also the development of unique building integrated components.

The objective of this research project: To capture both direct and diffuse solar radiation to produce higher efficiencies with concentration ratios over 3 in a plasmonically enhanced luminescent solar concentrator (PLSC);

  • To engineer composites (luminescent species (dye/QD) and Then optimized nanocomposite used to fabricate plasmonic solar concentrator optical device using moulding techniques.
  • To develop the first static building integrated PLSC component capable of achieving a concentration factor of 3 or more in diffuse solar radiation.
  • MNPs in polymer) for PLSC and PLDS and to determine, validate, and maximize manipulation of the optical properties of luminescent species through modifying the localized electrical boundary condition by exploiting the Plasmonic field.
  • To achieve record efficiency in a Luminescent Solar Concentrator by exploiting plasmonic coupling phenomena between metal nanoparticles and luminescent species (dye/QD) to enhance emission and alignment of MNP for directional emission.
  • Develop a simulation model to optimize the plasmonic coupling in the PLSC, consequently the size and shape to concentrate maximum solar radiation.
