Abstract

Spectral characteristics of some luminescent dyes, derivatives of xanthene and benzoxazinone groups, in a liquid polymer matrix, Triton x-100, have been studied. It is seen that Triton x-100 could serve as a suitable liquid matrix for the luminescent solar concentrators (LSCs).

Color-tunable multilayered laminated luminescent solar concentrators based on colloidal quantum dots
2023, Nano Energy
Luminescent solar concentrators (LSC) are a promising technology for building integrated photovoltaics (BIPV). Besides obtaining satisfactory efficiencies and aesthetic appeal, a simple and low-cost fabrication process is required to deploy large-scale LSCs. Herein, we introduced a facile and cost-effective fabrication method to obtain laminated LSC (L-LSC) devices. By optimizing the fabrication parameters, L-LSC based on polymer substrates exhibited higher efficiency (power conversion efficiency, PCE=0.24%, external photon efficiency, η_ext=4.14% and optical efficiency, η_opt=3.46%) compared to glass-based L-LSC (PCE=0.09%, η_ext=1.59%, $η_{opt}$ =1.76%) due to their excellent optical properties and good compatibility with the laminated emissive layer. Using the optimized L-LSC device, a color-tunable multilayered L-LSC structure is then proposed. By embedding different QDs into two interlayers, the color appearance of the device can be tuned, simultaneously improving the overall efficiency. This study presents a notable advancement towards a practical application of L-LSCs with a satisfactory efficiency and color aesthetics for sustainable BIPVs.

As many dye molecules have QYs close to 100% (e.g., Rhodamine 6G) and most of them operate in the UV and blue range of the spectrum, QY does not appear to be a serious barrier. Measurements have shown lower QYs for dyes fluorescing in the red and infrared regions where the silicon solar cells has its maximum sensitivity (Wood and Long, 1978; Kondepudi and Srinivasan, 1990), however, QY is improving (Jung et al., 2001). For an ideal LSC, the absorption and emission spectra should be well separated.
Recent research in Building Integrated Photovoltaics (BIPV) is reviewed with the emphases on a range of key systems whose improvement would be likely to lead to improved solar energy conversion efficiency and/or economic viability. These include invertors, concentrators and thermal management systems. Advances in techniques for specific aspects of systems design, installation and operation are also discussed.
Quantum dot solar concentrators: Electrical conversion efficiencies and comparative concentrating factors of fabricated devices
2007, Solar Energy
A novel, non-tracking concentrator is described, which uses nano-scale quantum dot technology to render the concept of a fluorescent dye solar concentrator (FSC) a practical proposition. The quantum dot solar concentrator (QDSC) comprises quantum dots (QDs) seeded in materials such as plastics and glasses that are suitable for incorporation into building façades. Photovoltaic (PV) cells attached to the edges convert direct and diffuse solar energy collected into electricity for use in the building. Small scale QDSC devices were fabricated. Devices have been characterised to determine current, voltage and power readings. Electrical conversion efficiencies, fill factors and comparative concentrating factors are reported.
Electric and dielectric properties of some luminescent solar collectors based on phthalocyanines and hematoporphyrin doped PMMA

In these devices solar energy is absorbed and concentrated by total internal reflection to the edge of the device, where it is converted into electricity using a solar cell facing the edge [7]. One of the most important requirements for LSC is a large Stokes shift, which is known to be a function of the dielectric constant (ɛ′) and the refractive index (n) of the substrate [8,9]. So, we concentrate to study the electrical and dielectric properties of PMMA free and mixed with three laser dyes: phthalocyanine, nickel-phthalocyanine and hematoporphyrin IX chloride.
The electrical properties: DC-electrical conductivity (σ_DC), AC-electrical conductivity (σ_AC), dielectric permittivity (ɛ′) and dielectric loss (ɛ″) for pure polymethylmethacrylate (PMMA) and mixed with phthalocyanine, Ni-phthalocyanine and hematoporphyrin IX chloride laser dyes have been investigated. The conductivity values for all polymer–dye samples are higher than that of the pure PMMA. For all investigated samples, at the constant temperature, the frequency dependence of (σ_AC) was found to obey the relation (σ_AC) = Aω^s. The results are discussed according to the correlated barrier hopping CBH mechanism from which the Coulomb well barrier of charge carriers (W_M) was calculated. For the dye-doped samples, the hematoporphyrin IX chloride mixed sample showed the larger value of (W_M) compared with the others. At all frequencies, ɛ′ values for doped samples are higher than that of pure one. This is due to a free volume enhancement offered by the large size of the dye molecule. Also, the addition of dyes to PMMA causes an increase in the intensity of the loss peak (ɛ″) accompanied by a shift in its position. The effect of chemical structure of investigated dyes on the electrical properties is discussed.
Polymethyl methacrylate mixtures with some organic laser dyes. I. Dielectric response
1999, Polymer Testing
Solid samples of polymethyl methacrylate (PMMA) free and mixed with coumarin-6 or fluorescein sodium organic laser dyes have been prepared by a casting method. The dielectric parameters such as dielectric permittivity (ϵ′) and dielectric loss (ϵ″) have been measured as a function of temperature and frequency. Both dyes have an increasing effect on both the magnitude and rate of increase of (ϵ′) with temperature. The absorption peaks obtained in the ϵ″(T) spectra were analysed and interpreted. For the pure polymer, two regions were distinguished in both the relaxation spectra and Arrhenius plot of relaxation times. These were assigned to a β process at lower temperatures and an αβ one at higher temperatures with activation energy values of 16.1 and 21.6 kcal/mol respectively. Coumarin-6 dye-doped sample exhibited an entirely plastification effect reflected in lower values of the temperature of ϵ″_max, the activation energy and β factor of the non-Debye behaviour for the distribution of relaxation times. On the other hand, in fluorescein sodium dye-doped sample, the presence of the dye hinders the α process of the host polymer due to intermolecular interactions between the polymer molecules and the solute dye.
