“…This complex absorbs light in the UV region (<350 nm) and emits it at 613 nm with an FQY of 86% in PMMA. In 2011, Katsagounos [161] showed four europium-based complexes with increased luminescence compared to the single europium ion and using these dyes in LSC-type downconverters increased the efficiency of multicrystalline-silicon solar cells up by 17%, for the complex with a pyridine derivate as a ligand.…”

Research on the luminescent solar concentrator (LSC) over the past thirty‐odd years is reviewed. The LSC is a simple device at its heart, employing a polymeric or glass waveguide and luminescent molecules to generate electricity from sunlight when attached to a photovoltaic cell. The LSC has the potential to find extended use in an area traditionally difficult for effective use of regular photovoltaic panels: the built environment. The LSC is a device very flexible in its design, with a variety of possible shapes and colors. The primary challenge faced by the devices is increasing their photon‐to‐electron conversion efficiencies. A number of laboratories are working to improve the efficiency and lifetime of the LSC device, with the ultimate goal of commercializing the devices within a few years. The topics covered here relate to the efforts for reducing losses in these devices. These include studies of novel luminophores, including organic fluorescent dyes, inorganic phosphors, and quantum dots. Ways to limit the surface and internal losses are also discussed, including using organic and inorganic‐based selective mirrors which allow sunlight in but reflect luminophore‐emitted light, plasmonic structures to enhance emissions, novel photovoltaics, alignment of the luminophores to manipulate the path of the emitted light, and patterning of the dye layer to improve emission efficiency. Finally, some possible ‘glimpses of the future’ are offered, with additional research paths that could result in a device that makes solar energy a ubiquitous part of the urban setting, finding use as sound barriers, bus‐stop roofs, awnings, windows, paving, or siding tiles.

“…Triazine-based ligands have excellent sensitization properties for the luminescence of europium up to 400-410 nm (Xue et al, 2010) and some of them display sizeable two-photon absorption cross-sections (Lo et al, 2011) so that in addition to dpbt (Scheme 1) several triazinyl ligands have been tested for use in LSCs (Scheme 2) (Katsagounos et al, 2011) to one end of which a multicrystalline silicon (m-Si) solar cell with 15% conversion yield was attached. No quantitative data on the photophysical properties of the metal complexes are given, but [Eu(NO 3 ) 3 (trz1) 2 ] appears to be the most luminescent and it is also the most effective in LSCs.…”

“…The work of Katsagounos et al (2011) is also worth mentioning. These authors put an m-Si cell with initial quantum efficiency of 15% into contact with 1 and 3 LSC layers doped with [Eu(NO 3 ) 3 (trz1)] (Scheme 2) and achieved improvements reaching 17% and 28%, respectively, corresponding to absolute 2.5% and 4.2% increases (see Section 2.3).…”

“…The luminophore in the waveguide plays a crucial role on the performance of LSCs. Katsagounos et al [14] introduced a kind of europium complexes (EuðNO 3 Þ 3 ðtrz-pyÞ 2 ·CH 3 CN) as light concentrators into the LSC, and the photocurrent was increased by a 28% maximum. Li et al [15] reported a new quantum dots (QDs) LSC integrated with heavy metal free CuInS 2 ∕ZnS core/shell QDs with a large Stokes shift and high optical efficiency.…”

Luminescent solar concentrators with a bottom-mounted photovoltaic cell: performance optimization and power gain analysis

Polymethyl methacrylate (PMMA) plate luminescent solar concentrators with a bottom-mounted (BM-LSCs) photovoltaic (PV) cell are fabricated by using a mixture of Lumogen Red 305 and Yellow 083 fluorescent dyes and a commercial monocrystalline silicon cell. The fabricated LSC with dye concentrations of 40 ppm has the highest power gain of 1.50, which is the highest value reported for the dye-doped PMMA plate LSCs. The power gain of the LSC comes from three parts: the waveguide light, the transmitted light, and the reflected light from a white reflector, and their contributions are analyzed quantitatively. The results suggest that the BM-LSCs have great potential for future low-cost PV devices in building integrated PV applications.
