“…[100] Recent examples of hybrid materials used in LSCs comprise polymers doped with QDs, [105,106] metal halide nanocluster blends [107] and organic dyes, [104] Eu 3+ -based bridged silsesquioxanes, [108][109][110] and di-and tri-ureasils doped with organic dyes and Eu 3+ $-diketonate complexes. [101,[111][112][113] An intriguing example of lightweight and mechanically flexible high-performance waveguiding photovoltaics is the fabrication of cylindrical LSCs of plastic optical fibers (POFs) coated (bulk fibers) or filled (hollow-core fibers) with Rh6G-or Eu 3+ -doped organic-inorganic hybrids ( Figure 8D-G). [101,112] Cylindrical LSCs have a large potential compared with that of planar ones, despite the very small number of examples involving short length (10 −2 m) bulk or hollow-core POFs.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

Four different dye-doped polymer optical fibers (POFs) have been fabricated following a two-step fabrication process of preform extrusion and fiber drawing, using poly-(methyl methacrylate) (PMMA) as host material and dye derivatives from perylene and naphtalimide as active dopants. The side illumination technique (SIT) has been employed in order to determine some optical properties of the fabricated fibers, such as the side illumination coupling efficiency, optical loss coefficients, and their performance under solar simulator excitation. The aim of this work is to investigate the performance of the manufactured fibers for fluorescent lighting applications, specially targeting on fluorescent fiber based solar concentrators.

“…Whereas in the former case the hollow‐core was left empty, for the COP LSCs, the hollow core was filled with a rod of dye‐doped COP. A recent example, developed by some of us, involves cylindrical LSCs based on commercial plastic optical POFs coated with an organic–inorganic hybrid layer containing Eu(tta) 3 ·2H 2 O (tta − = 2‐thenoyltrifluoroacetonate) . Coated LSCs are more efficient when compared with homogeneously doped ones because of a higher trapping efficiency and reduced parasitic losses because of self‐absorption and scattering from impurities .…”

Luminescent solar concentrators (LSCs) are cost‐effective components easily integrated in photovoltaics (PV) that can enhance solar cells' performance and promote the integration of PV architectural elements into buildings, with unprecedented possibilities for energy harvesting in façade design, urban furnishings and wearable fabrics. The devices' performance is dominated by the concentration factor (F), which is higher in cylindrical LSCs compared with planar ones (with equivalent collection area and volume). The feasibility of fabricating long‐length LSCs has been essentially limited up to ten of centimetres with F < 1. We use a drawing optical fibre facility to easily scale up large‐area LSCs (length up to 2.5 m) based on bulk and hollow‐core plastic optical fibres (POFs). The active layers used to coat the bulk fibres or fill the hollow‐core ones are Rhodamine 6G‐ or Eu3+‐doped organic–inorganic hybrids. For bulk‐coated LSCs, light propagation occurs essentially at the POFs, whereas for hollow‐core device light is also guided within the hybrid. The lower POFs' attenuation (~0.1 m−1) enables light propagation in the total fibre length (2.5 m) for bulk‐coated LSCs with maximum optical conversion efficiency (ηopt) and F of 0.6% and 6.5, respectively. For hollow‐core LSCs, light propagation is confined to shorter distances (6–9 × 10−2 m) because of the hybrids' attenuation (1–15 m−1). The hollow‐core optimised device displays ηopt = 72.4% and F = 12.3. The F values are larger than the best ones reported in the literature for large‐area LSCs (F = 4.4), illustrating the potential of this approach for the development of lightweight flexible high‐performance waveguiding PV.
