“…[130] Some recent works have developed luminophores endowed with AIE [110] as a possible approach to limit SA. [131][132][133][134][135][136][137] In AIE systems, the energy cost required to form the emissive aggregated state should result in a larger Stokes shift than that of the chromophore in diluted solution. Banal et al investigated a small thin-film LSC (1 × 1 × 0.1 cm, G = 2.5) with tetraphenylethene (TPE) (13) (the archetype of AIE-gen) (Figure 9), as emitter.…”

Luminescent solar concentrators (LSCs) are optical systems that absorb, convert, and concentrate solar light by means of photoluminescence of an emitting material embedded in a transparent waveguide. LSCs combine large possibilities of variation of shape, flexibility, color, and transparency and can operate under direct or diffuse light. LSCs were actively investigated in the period 1975–1985 in view of photovoltaic (PV) conversion. After 20 years of sleep, research on LSCs has reemerged in the first years of the millennium driven by their potential application for PV conversion in built environment. Research on LSCs aims at the development of new active and passive components, namely emitting and light‐guiding materials, and at the reduction of the loss factors associated with the elemental processed involved in the operation in order to improve power conversion efficiency. After a brief historical account, the operating principles, characterization, components, technology, and applications are reviewed. Finally, the performance of LSCs are critically discussed in a global perspective with particular emphasis on the basic contradiction between light concentration and conversion efficiency leading to some suggestions for future development of the topic.

“…This parameter provides a direct estimation of the fundamental properties of a LSC (i.e., to collect and concentrate incident light) as it is directly influenced by all intrinsic loss mechanisms occurring to photons prior to being successfully collected at the edges of the waveguide (Debije and Verbunt, 2012;Moraitis et al, 2018). To tackle some of these loss mechanisms, research in the field of LSCs has been traditionally driven by the development of highly emissive luminescent species and by the engineering of more efficient device assemblies, as recently summarized in some excellent review articles (Debije and Verbunt, 2012;McKenna and Evans, 2017;Mazzaro and Vomiero, 2018;Pucci, 2018).…”

Luminescent solar concentrators (LSCs) have attracted increasing attention in the past few years as appealing solar energy technology for the seamless integration of photovoltaic (PV) systems into the built environment. Traditionally, research in this field has focused on two main aspects: the optimization of the device assembly, in the quest for more efficient architectures to maximize collection, transport, and conversion of photons into usable electrical energy; the development of novel, highly emissive luminescent species, to ensure broad light collection and efficient photon emission. Only recently, the attention has also been directed toward the selection and development of suitable host matrix/waveguide materials with appropriate optical properties, sufficient chemical compatibility with the guest luminescent species, good processability for easy device fabrication and prolonged durability in outdoor operation. In addition to consolidated polymeric systems based on polyacrylates or polycarbonates, in recent years different examples of alternative host matrix systems have been proposed, characterized by peculiar chemical, physical and optical characteristics specifically designed to meet the stringent requirements of the LSC technology. This mini-review will focus on recent developments in the design of new host matrix materials for LSC applications. An overview of the most recent examples of novel LSC host matrices will be provided here, mainly focusing on new polymers, polymer-based organic-inorganic hybrids and multifunctional organic systems. Finally, opportunities and challenges in the field will be considered in view of the effective exploitation of the LSC technology in real application scenarios.
