Case 13289

Materials for Luminescent Solar Concentrators

Keywords:

Luminescent solar concentrator, LSCs, up-conversion, anti-stokes emitters, PV

Applications:

Photovoltaic Cells

Problem:

Anti-stokes emitters are inefficient at the up-conversion process.

Technology:

This invention introduces an efficiently-emitting dye, which increases the overall efficiency of the up conversion process. Up-converted radiation in the anti-stokes material is transferred through near-field energy transfer to the dye, which efficiently absorbs infrared light and re-emits it at higher energies, with a more efficient up-conversion process.

Advantages:
  • Increases the efficiency of the up conversion process of anti-stokes emitters
  • Reduce cost per watt of generated power and the system cost
