WebJul 11, 2014 · The optical efficiency of the solar concentrator with SOE I of parameter set (18, 14) was good (74.9%) at incidence angle of 1°; however, the optical efficiency was only 80.8% at incidence angle of 0° (normal incidence). Therefore the parameter set (18, 14) was not selected as a feasible parameter set for SOE I. (b) (a) (b) (a) (b) (a) (b) Figure 3 WebLuminescent solar concentrators (LSCs) generally consist of transparent polymer sheets doped with luminescent species. Incident sunlight is absorbed by the luminescent species and emitted with high quantum efficiency, such that emitted light is trapped in the sheet and travels to the edges where it can be collected by solar cells.

WebThe Luminescent solar concentrators (LSCs) consist of a film containing optically active centers, converting part of the absorbing radiation into a specific emitting wavelength, when exposed to sunlight. The emitting centers are also crucial factors regarding their efficiency, so the selection must be done carefully.
WebLuminescent solar concentrators (LSCs) use dye molecules embedded in a flat-plate waveguide to absorb solar radiation. Ideally, the dyes re-emit the absorbed light into waveguide modes that are coupled to solar cells. But some photons are always lost, re-emitted through the face of the LSC and coupled out of the waveguide. In this work, we …
