Förster Resonance Energy Transfer in Luminescent Solar Concentrators

Abstract

Luminescent solar concentrators (LSCs) are an emerging technology to collect and channel light from a large absorption area into a smaller one. They are a complementary technology for traditional solar photovoltaics (PV), particularly suitable for application in urban or indoor environments where their custom colors and form factors, and performance under diffuse light conditions may be advantageous. Förster resonance energy transfer (FRET) has emerged as a valuable approach to overcome some of the intrinsic limitations of conventional single lumophore LSCs, such as reabsorption or reduced quantum efficiency. This review outlines the potential of FRET to boost LSC performance, using highlights from the literature to illustrate the key criteria that must be considered when designing an FRET‐LSC, including both the photophysical requirements of the FRET lumophores and their interaction with the host material. Based on these criteria, a list of design guidelines intended to aid researchers when they approach the design of a new FRET‐LSC system is presented. By highlighting the unanswered questions in this field, the authors aim to demonstrate the potential of FRET‐LSCs for both conventional solar‐harvesting and emerging LSC‐inspired technologies and hope to encourage participation from a diverse researcher base to address this exciting challenge.

Performance Evaluation of Solid State Luminescent Solar Concentrators Based on InP/ZnS-Rhodamine 101 Hybrid Inorganic–Organic Luminophores

“…Multiple luminophore LSCs have been a successful approach to LSC research. ,, Multiple luminophore LSCs are defined as LSCs composed of multiple organic, inorganic, or organic and inorganic luminophores. By exploiting energy transfer between components, reabsorption has been reduced in many cases while maintaining broad absorption spectraideal for solar sensitization.…”

An autonomous power temperature sensor based on window-integrated transparent PV using sustainable luminescent carbon dots

“…12 Materials with absorption in the ultraviolet (UV)/blue spectral region have been sought, as they result in transparent and colourless waveguides, ideal for windows, contributing to aesthetics and avoiding distortion of the spectrum of the natural light, which typically happens in highly efficient luminophores with signicant absorption in the visible region. 13,14 Examples include organic synthetic dyes, quantum dots (QDs), lanthanide ions, and organic molecules from natural renewable sources. [15][16][17] In particular, QDs present excellent optical properties (e.g., size, shape, chemical composition, tuneable absorption spectra, structurally engineered Stokes shi, high photoluminescent quantum yield (f) values, and enhanced photostability) compared to conventional organic dyes and have attracted a lot of attention as uorophores for LSCs.…”

Efficient detection ofl-aspartic acid andl-glutamic acid by self-assembled fluorescent microparticles with AIE and FRET activities

“…Moreover, it is worth mentioning that TPE and its derivatives are often used as donor fluorescent groups for the Förster resonance energy transfer (FRET) phenomenon. 11 FRET is a distance-dependent photophysical process, in which energy is transferred from an excited donor fluorophore to a proximal ground-state acceptor fluorophore by means of non-radiative dipole–dipole coupling. Generally, the FRET process requires a suitable distance between the two fluorescent groups (generally less than 100 Å).…”
