“…LR has been selected as reference as it is considered the state-of-the-art in dyes for LSC applications (Debije and Verbunt, 2012) and its use has been reported in many recent papers (Dienel et al, 2010;Sark et al, 2008;Griffini et al, 2013;Bakr et al, 1999). LR shows a quantum yield (QY) of about 1 even at high concentration (>1 mmol) in polymers and in the solid state (Al-Kaysi and Sang, 2006) and a good photostability (Reisfeld et al, 1994).…”

We introduce a new method for the prompt and effective evaluation of the optical efficiency of different sets of luminescent solar concentrators (LSC) based on dye-doped poly(methyl methacrylate) thin films. The procedure founded on the realization of a home-build apparatus (PeryRoom), which allowed for a fast and reliable measurement of the generated photocurrents profiting of the use of a photodiods system. The photocurrents were analyzed by means of a simple model inspired by the work of Goetzberger and Greube (1977) and rationalized in terms of different dye characteristics and film thickness. The procedure was eventually validated by comparing the optical efficiencies measured by using a Si-based photovoltaic module. Overall, the present results support the use of PeryRoom for the optimization of the current state-of-art LSC systems

“…Recently, concepts for overcoming the most severe problems of LSCs have been proposed and this has created renewed interest. [96][97][98][99][100] The severe problem of self-absorption can be overcome by using the antenna systems and materials explained in Figure 9, as we have discussed recently. [80,47] In order to get a first idea regarding the photophysical properties of the chromophores, we show in Figure 10 the absorption and fluorescence spectra of diluted solutions of HY3G in CHCl 3 and Ox + in MeOH.…”

Designing Dye–Nanochannel Antenna Hybrid Materials for Light Harvesting, Transport and Trapping

We discuss artificial photonic antenna systems that are built by incorporating chromophores into one-dimensional nanochannel materials and by organizing the latter in specific ways. Zeolite L (ZL) is an excellent host for the supramolecular organization of different kinds of molecules and complexes. The range of possibilities for filling its one-dimensional channels with suitable guests has been shown to be much larger than one might expect. Geometrical constraints imposed by the host structure lead to supramolecular organization of the guests in the channels. The arrangement of dyes inside the ZL channels is what we call the first stage of organization. It allows light harvesting within the volume of a dye-loaded ZL crystal and also the radiationless transport of energy to either the channel ends or center. One-dimensional FRET transport can be realized in these guest-host materials. The second stage of organization is realized by coupling either an external acceptor or donor stopcock fluorophore at the ends of the ZL channels, which can then trap or inject electronic excitation energy. The third stage of organization is obtained by interfacing the material to an external device via a stopcock intermediate. A possibility to achieve higher levels of organization is by controlled assembly of the host into ordered structures and preparation of monodirectional materials. The usually strong light scattering of ZL can be suppressed by refractive-index matching and avoidance of microphase separation in hybrid polymer/dye-ZL materials. The concepts are illustrated and discussed in detail on a bidirectional dye antenna system. Experimental results of two materials with a donor-to-acceptor ratio of 33:1 and 52:1, respectively, and a three-dye system illustrate the validity and challenges of this approach for synthesizing dye-nanochannel hybrid materials for light harvesting, transport, and trapping.

Luminescent Solar Concentrators (LSCs) have been proposed in the 1970s as cheap planar concentrators for residential applications and nowadays represent a novel idea with excellent perspectives for building integration photovoltaics. The interest in LSCs has increased in the last years, due to improved stability of luminescent dyes, the introduction of quantum dots and nanorods and the overall reported increase in module efficiency. Computational methods have been suddenly applied as an important tool for the description of light dynamics in LSCs. With "raytracing methods" light is described as particle-like (photons) and each particle is tracked. It is precious tool for the description of absorption/reemission events, refraction and internal reflection in LSCs. It is also a very useful approach for the description of LSC edge effects, which may be well described by means of basic geometrical optics and are the subject of this work. The impact of scattering layers on the backside of LSCs is analysed in detail both experimentally and computationally. Results give evidence of the non-wavelength dependent impact of backside diffusers to the external quantum efficiency of LSCs and thus to their overall performance. A possible design of LSC as smart windows in photovoltaic facades is also suggested, where the benefits of the edge effects described are taken into account.
