The surface and edge emissions from dye-filled and dye-topped polycarbonate and polymethyl methacrylate luminescent solar concentrators were measured. We demonstrate that about 40-50% of the absorbed light energy (and 50-70% of the photons) is lost through the top and bottom surfaces of the filled waveguide. In most cases the escape cone losses are greater at the top than the bottom surface.

    • "Organic luminescent dyes are very attractive as they have high abundance, low cost and allow simple processing into LSCs but they suffer from self-absorption losses that decrease the amount of luminescence that reaches the solar cell up to a factor of 3, depending on LSC size, compared to no self-absorption. [6] [7] [8] In addition, best available organic LSC dyes like Rhodamine 6G [9] and Red 305 [10] only absorb about 30% of the solar spectrum (o600 nm) which is typically just 50% of an amorphous silicon solar cell. This results in limited power efficiency and in brightly colored LSCs that do not allow for large scale penetration into the built environment. "

    ABSTRACT: The optical and luminescence properties of CaI2 and NaCl doped with divalent thulium are reported for solar energy applications. These halides strongly absorb solar light from the UV up to 900 nm due to the intense Tm2+ 4f13 ->4f125d1 electronic transitions. Absorption is followed by emission of 1140 nm light due to the 2F5/2 -> 2F7/2 transition of the 4f13 configuration that can be efficiently converted to electric power by thin film CuInSe2 (CIS) solar cells. Because of a negligible spectral overlap between absorption and emission spectra, a luminescent solar concentrator (LSC) based on these black luminescent materials would not suffer from self-absorption losses. The Tm2+ doped halides may therefore lead to efficient semi-transparent power generating windows that absorb solar light over the whole visible spectrum. It will be shown that the power efficiency of the Tm2+ based LSCs can be up to four times higher compared to LSCs based on organic dyes or quantum dots.

    • "In addition, the concentration mechanism prevents the PV cell from over-heating and, finally, LSCs have the advantages of improved architectural integration and lower cost. The most common materials currently used for the production of doped polymer sheets are PMMA and (poly)carbonate (PC) because of their high transparency and durability under exposure to sunlight [10] [11], but thermoplastic copolymers may be used for this application as well, as pointed out by Bhaumik et al. [12]. "

    ABSTRACT: We here report on our investigation of the properties of polysiloxane rubber waveguides doped with Lumogen Red 305 for the production of luminescent solar concentrator (LSC) devices. Samples with different dye concentrations were produced and their optical properties were characterized by absorption and fluorescence spectroscopy measurements. Moreover, different concentrations of Au nanoparticles were dispersed in the matrix in order to study the possibility of enhancing the fluorophore fluorescence yield. The light output from the edges of the samples, irradiated with a solar simulator was measured with an integrating sphere and the light yield was compared to that obtained with polycarbonate waveguides containing the same amount of the fluorescent dye BASF Lumogen Red305. Preliminary results from measurements with a GaAs photovoltaic cell and a silicon photodiode coupled to the polysiloxane waveguides are also presented.

    • "Finally, the perylene perinone waveguide will be able to absorb the light escaping from the rear surface of the Red305 waveguide. As a significant fraction of the absorbed photons are lost through the surfaces of the waveguide [15], this latter effect could be significant. "

    ABSTRACT: We describe the synthesis of a dye based on a perylene perinone and evaluate its potential as the functional material for use in the luminescent solar concentrator (LSC). The dye extends the absorption wavelength of LSCs using the perylene-based dye Lumogen Red 305 by more than ~50 nm, translating into the collection of potentially 25% more photons at a reasonable fluorescent quantum yield and photostability. When the new perinone is used in a two-waveguide LSC in conjunction with Red 305, the integrated edge emission of the total LSC system may be increased more than 24% when compared to the Red 305 dye alone.
