Traditional concentrating photovoltaic (CPV) systems utilize multijunction cells to minimize thermalization losses, but cannot efficiently capture diffuse sunlight, which contributes to a high levelized cost of energy (LCOE) and limits their use to geographical regions with high direct sunlight insolation. Luminescent solar concentrators (LSCs) harness light generated by luminophores embedded in a light-trapping waveguide to concentrate light onto smaller cells. LSCs can absorb both direct and…

Ultralight Luminescent Solar Concentrators for Space Solar Power Systems
Space-based solar power systems (SSPS) offer a renewable source of energy generation that features higher power production than terrestrial photovoltaics (PV) systems with visibly unobstructed access
Unlocking Higher Power Efficiencies in Luminescent Solar Concentrators through Anisotropic Luminophore Emission.
TLDR
It is shown that luminescent concentrator conversion efficiency can be increased from the current record value of 7.1-9.6% by incorporating anisotropy, and that for high LSC performance, waveguide losses are as important as the luminophore quantum yield.
