Luminescent solar concentrators (LSCs) have the potential of converting solar energy into electricity more cheaply than a standard photovoltaic (PV) panel. LSCs are thin plates of plastic or glass that contain fluorescent material throughout the plat

Combining multiple organic dyes to form a fluorescence resonance energy transfer (FRET) network is a useful strategy for extending the spectral range of sunlight absorbed by a luminescent solar concentrator (LSC). Excitation transfer out of the highe

The performances of luminescent solar concentrators (LSCs) made with two versions of quantum dots (QDs) with CdSe cores and ZnS shells are compared to LSCs containing the organic dye, Lumogen ® F Red 300 (LR), to assess the viability of QD LSCs. In

The spectral range of sunlight absorbed by a luminescent solar concentrator (LSC) is increased by using multiple dyes. Absorption, fluorescence, and fluorescence excitation spectra, and relative light output are reported for LSCs made with one, two,

When dye molecules are placed into a solid, like a polymer matrix, the opportunity exists for resonant excitation energy transfer from the solid to the dye. We observe a 51% excitation transfer efficiency from polystyrene to the fluorescent dye BODIP
