“…As an example, a polymethyl methacrylate (PMMA) LSC doped with a Lumogen F Red 305 dye with a concentration of 115 ppm is considered with the absorbance and emission intensity as determined by Desmet et al [20] and shown in Fig. 2.…”

Analytical equations quantifying self-absorption losses in circular luminescent solar concentrators (LSCs) are presented that can easily be solved numerically by commercial math software packages. With the quantum efficiency, the absorption and emission spectra of a luminescent material, the LSC dimensions, and the refractive index as the only input parameters, the model gives an accurate account of the decrease of LSC efficiency due to self-absorption as a function of LSC radius, thickness, and luminescence quantum efficiency. Results give insight into how many times light is reabsorbed and reemitted, the red shift of the emission spectrum, and on how multiple reabsorptions and reemissions are distributed over the LSC. As an example case the equations were solved for a circular LSC containing a Lumogen F Red 305 dye with 80% luminescence quantum efficiency, and it follows that for an LSC with a 50 cm radius the self-absorption reduces the number of photons reaching the LSC edge by a factor of four compared to the case when there would be no self-absorption. The equations can just as well be solved for any material for which the optical properties are known like type I and type II quantum dots.

“…The window-like qualities of these new materials, such as letting the shape of the visible spectrum remain unaltered, make them suitable as BIPV. A typical LSC is either a polymer plate (mostly PMMA) doped with luminophores, or a glass sheet carrying a luminescent coating [4][5][6]. Figure 1 illustrates the luminescent solar concentrating process.…”

“…Many approaches have been reported to overcome these obstacles and improve the efficiencies. For example, stacking dual waveguides containing different dyes has been suggested as a means to harvest broad band solar irradiation [15]. Patterning of the dye layer is also an effective method for minimizing reabsorption losses and increasing emission efficiencies [16,17].…”
