Flexible, Front-Facing Luminescent Solar Concentrators Fabricated from Lumogen F Red 305 and Polydimethylsiloxane

Figure 6

Absorbance spectra of bulk-doped, thin-film, and clear LSC waveguides. The thin-film waveguide had a 56% lower absorbance than the bulk-doped waveguide at 565 nm. Quenching and self-absorption may limit thin-film device performance at higher dye concentrations, resulting in devices that are optimized with lower optical densities.
