Luminescent solar concentrators based on thin films of polymethylmethacrylate on a polymethylmethacrylate support

Bent fluorescent solar concentrators (BFSCs): Spectroscopy, stability and outdoor performance

“…and give a value of g opt = 23.61%. This value is remarkably high compared with the values published before, this allowed us to choose the optimum dye concentration for PMMA/SiO 2 FSCs [13,14].…”

Thirty Years of Luminescent Solar Concentrator Research: Solar Energy for the Built Environment

“…Rhodamines, like Rhodamine 6G, and coumarins, like Coumarin 6 (also known as Coumarin 540), belong to the group of dyes mentioned in the earliest stages of LSC research, [16,112] while the perylenes and perylenebisimides are mostly mentioned in the more recent papers on LSCs, and were first described for use in LSCs in the late eighties. [96,119] Rhodamines are known for their high quantum yields and high molarextinction coefficients, but also for their small Stokes shifts. These small Stokes shifts lead to much re-absorption and consequently to increased LSC losses, both surface and quantum (nonradiative) losses.…”

“…[111] Since the first papers on LSCs, organic dyes have been investigated as luminophores of choice due to their solubility, high fluorescence yields, and large absorption coefficiencts. The dyes investigated as possible components of LSCs belong to the following classes of molecule: bipyridines, [25] coumarins, [40,48,49,[112][113][114][115][116] dicarbocyanine iodides, [48] dicyano methylenes, [20,48,49,113,117] lactones, [114] naphtalimides, [114,116,118] oxazines, [48] perylenes and perylenebisimides, [40,46,93,96,[114][115][116][118][119][120][121][122][123] perylenebisimidazoles, [93] phtalocyanines, [124] phycobilisomes, [125] porphyrins, [20,124] pyrromethenes, [114] rhodamines, [16,18,48,49,[111][112]…”

Optical and thermal spectroscopic studies of luminescent dye doped poly(methyl methacrylate) as solar concentrator

“…Many experimental efforts have been made for a large plate area of LSCs. 3 The effect of the geometrical shape of the bulk concentrators doped with different luminescent dyes on the conversion coefficient and the principles of LSCs in yearly, monthly, and daily correlations for dye photodegradation and optical efficiency have been discussed. 4 -7 In the present work we study the transition mechanism within the wide band gap of LSC materials to attain the best conditions under which these LSCs will have high thermal stability and photostability and enhance the solar cell conversion efficiency.…”
