“…[94] The effect of the thickness of the thin film on efficiency has been investigated. [197] Thin-film and bulk LSC doped with the same perylene dye have been compared on devices of 2.5 × 2.5 × 0.1 cm doped with various dye concentrations and it was concluded that bulk LSCs lead to better results than thin films. [198] In recent years, thin-films LSCs have been investigated by many groups, [107,119,131,153,157,161,162,183,184] but until now, only one example of thin-film LSC of more than 100 cm 2 area giving C > 1 has been reported.…”

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.

“…[21] Although LSC-PV devices that exploit the optical features of organic luminophors are well documented, [5,12,14,16,[22][23][24] alternative and effective red-emitting fluorophores to perylene derivatives are not available yet. Recent research has been focused on the use of (dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) fluorophore ( Figure 1), [17,[25][26][27], but the optical performances of the derived PMMA-based LSC appeared still lower than the state-of-the art. [26] fluorescence quantum yields and exceptional thermal and photostability, which make them excellent building blocks for many applications.…”

“N-alkyl diketopyrrolopyrrole-based fluorophores for luminescent solar concentrators: Effect of the alkyl chain on dye efficiency”

et al. 2016

We report on the preparation of luminescent solar concentrators (LSCs) made of poly(methyl methacrylate) (PMMA) thin films doped with six new diketopyrrolopyrrole (DPP) fluorophores obtained in good yields by using simple N-alkylation and direct C-H arylation synthetic strategies. Spectroscopic investigations in solution and in PMMA thin films combined with photocurrent measurements revealed that the branched alkyl chains were efficient in preventing DPP segregation from the PMMA matrix thanks to their higher steric hindrance. The aromatic substituent was found to expand DPP conjugation but favoured DPP adverse aggregation, thus affecting fluorescence emission and photocurrents of PMMA films. The worthwhile combination of the appropriate alkyl chain and aromatic moieties assured to achieve optical efficiency of 6.8% that was comparable to that of PMMA LSCs of the state-of-the art (7.2%).

This manuscript is dedicated to Professor Mitsuo Sawamoto's outstanding achievements in polymer chemistry and recognizes his recent retirement from 40 years of exceptional service to Kyoto University.ABSTRACT: The use of luminescent solar concentrators (LSCs) offers an alternative approach to integrating photovoltaic technologies into the built environment. The research on LSCs has bloomed in the past decade in terms of searching for novel device architectures, developing new luminescent species, and employing unique host materials. This article will provide a concise review on LSCs and focus on the polymer host materials used in LSCs.Finally, we provide a brief outlook on the future development of this research area, particularly on the polymers used as host materials and luminescent species for LSCs.
