Applications for Luminescent Solar Concentrators


Indoor application of luminescent solar concentrator (LSCs)


Power wireless sensors, network nodes, small appliances, displays, systems monitoring, electrical grid power distribution systems, even the human body


High efficiency degradation for photovoltaic devices that scavenge or harvest power from ambient indoor lighting


This invention uses LSCs coupled with solar cells in indoor applications to compensate for the efficiency degradation caused by low illumination conditions. Optical concentrators concentrate light by the combination of refraction, reflection, absorption and subsequent waveguide emission. PVs with visible band gaps are used in concentrated configuration to maximize power conversion efficiency.

  • Increased electrical output
  • Compatible with both diffuse and direct illumination
  • Simultaneous conversion of light absorbed over multiple collector faces
  • Prevent overheating the solar cell by concentrating lower ambient light intensity
