ABSTRACT Aiming at net‐zero emissions, most international and national policies focus on sustainable development goals. Hence, there is an immediate need for replacing carbon‐intensive materials with biomaterials. In this respect, article presents a road‐map moving from polymeric to waveguides in optical devices. Previous reports indicate that luminescent fibres exhibit better photon concentrations of nearly 30%–33% higher than flat‐plate waveguides. It also verified the in‐out ratio increases by 3.44 times when waveguide geometry changed planar equivalent area fibre bundle same luminophore. Meanwhile, transparent wood (Twood) gaining attention as green alternative acrylic sheets. The structure function conforms well fibre‐based solar concentrators (LSCs). Therefore, it intriguing compare Twood intrinsic micro fibrillary interior LSC natural alternative. This review provides in‐depth analysis, emphasizing benefits associated challenges using cylindrical over LSCs. paper collects compares phenomenon light guiding LSCs Twood. important consider key points discussed here while making transition towards

Luminescent Solar Concentrators (LSCs) are a type of light concentrating devices which offer several advantages over other optical methods, like the possibility working with diffuse and appealing aesthetics, makes them an ideal technology for their integration in building's facades urban settings. In order to improve effectiveness foster large-scale adoption, solutions lower impact production extend lifetime would be extremely beneficial. Photostability is crucial fluorophores used LSCs, as they have endure extended sunlight exposure years. UV radiation can alter structure organic emitters, reducing LSC efficiency causing panel replacement, economic costs environmental implications. this study, two push-pull dyes comprising distorted heptagonal inclusions—namely, Peri2F Nap2Car—were investigated emitters bulk PMMA-based LSCs fabricated employing chemically regenerated monomers (r-MMA). Compared use virgin monomer, Global Warming Potential slab about four times smaller, thereby enhancing sustainability encouraging circularity fabrication. The most effective Peri2F/r-PMMA system yielded ηdev 0.7%, than that state-of-the-art emitter LR305. Remarkably, however, showed far superior resistance photodegradation. Forecast analysis estimated containing 100 ppm match LR305 performance r-PMMA after 1 year use, less 2% decrease initial emission intensity.
