“…[183] More recently, the same group reported a η opt of 34.7% for a perovskite LSC of unspecified dimensions. [184] CH 3 NH 3 PbBr 3 embedded in a PMMA was used to fabricate bulk LSCs of 5 × 3 × 0.5 cm in a mirror surrounded configuration (G = 10). Under AM 1.5 simulated solar light, the attached PV cells present a PCE of 9.20% in the absence of LSC and 5.44% at the LSC output, suggesting a C value of ≈0.60, while a pure PMMA device gave PCE of 3.24%, underlining once again the problems posed by very small LSCs.…”

“…[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.

“…One of the most significant advantages of LSC‐enabled solar cells is their ability to utilize both direct and diffuse sunlight, thereby negating the necessity of a tracking mechanism. [ 7 ] This allows LSCs to be incorporated into otherwise difficult architectures, such as vertical, or even nonplanar surfaces, making them far better suited as building integrated PVs. Another advantage is the versatility LSCs offer in their choice of appearance, where wavelength‐selectivity allows both color and transparency to be varied to suit the requirements of installation, such as in “smart” windows.…”

“…The active materials in LSCs must possess high photoluminescence quantum yield (PLQY) and broadband absorption. [ 1,7,11 ] The most commonly used fluorescent components include organic dyes and semiconductor quantum dots (QDs) such as CdSe/CdS, CdSe/ZnS, PbS, and Si. [ 1,2,5,6,12–16 ] The highest power conversion efficiency (PCE) to date is 7%, achieved in a dye‐based LSC when it is coupled to GaAs photovoltaic (PV) cells.…”

“…In particular, as the LSC is scaled up and G gets larger, the harder it is to achieve high efficiencies. For example, while optical efficiency η opt in the range of 20–40% has been reported in small LSCs [ 5,7,16,18 ] with G ≤ 30, η opt of large area LSCs with G ≥ 45 ranges from 1% to 2.6%. [ 19–21 ] The biggest hurdle that prevents LSCs from practical implementation is this matter of scalability, which arises from “self‐absorption” (SA) losses.…”

Organo‐metal halide perovskites (OMHPs) are currently one of the most exciting candidates for photovoltaics. However, their impact in other areas related to carrier photogeneration, such as in luminescent solar concentrators (LSCs), has been limited. OMHP thin films have demonstrated encouraging results as LSCs, but for a scalable platform with minimal losses, discrete emitters are preferable. Perovskite quantum dots (PQDs) possess higher photoluminescence quantum yield (PLQY) than their thin film counterparts, and have the added advantage of size tunability, which make them well‐suited as LSC active media. However, since PQDs are not amenable to Stokes shift modulation, large‐scale samples will suffer from increased self‐absorption (SA) losses. In this work, a facile dip‐coating approach is established to fabricating large‐scale LSCs with CH3NH3PbBr3 (methylammonium lead bromide) PQDs by leveraging their plasmonic interactions with gold nanoparticles (AuNPs) to offset SA losses. Optical characterization through emission, lifetime, and spatially resolved photoluminescence measurements provide insight into the effect of plasmon resonance on deposited PQDs, and leveraging this AuNP‐PQD coupling, 2.87% efficiency is achieved in a 100 cm2 LSC with a geometric gain of 50.

Luminescent solar concentrators (LSCs) are capable of absorbing solar light over a large area, which subsequently converts light into luminescence at a red-shifted wavelength and then redirects it to a smaller target to increase the per-unit yield of photovoltaic devices. Among various LSC materials, perovskite nanocrystals (NCs) have attracted great attention due to their adjustable band gap, multi-exciton effect, and good stability. In this review, a brief introduction of LSCs, including their advances and principles, is given, followed by a summary of perovskite-NCs-based LSCs. The selected examples for component optimization of inorganic perovskite NCs are outlined after an introduction to the structure and properties of perovskite NCs. The absorption and/or emission peaks of all-inorganic and inorganic-organic hybrid perovskite NCs can be efficiently regulated, which not only increases the Stokes shift but also improves the stability. Excellent performance and operability show a bright application prospect of perovskite NCs in the field of LSC applications.
