“…The current obtained highest optical efficiency (2.4% under one sun illumination) is comparable with those reported for the LSCs based on perovskite NCs and still lower than the LSCs based on QDs ( Table 1 ). The higher optical efficiency in 0D perovskites compared to 3D perovskites is due to their less absorption and emission overlap. We also measured the internal quantum efficiency (IQE) of the LSCs with Cs 4 PbBr 6 concentration of 4.5 wt%.…”

“…Among various types of fluorophores, perovskite NCs have attracted a lot of attention as building blocks in LSCs, in view of their size/composition‐dependent absorption and emission spectra, high brightness with a PL QY up to 100%, and facile wet‐chemistry synthesis . For example, with the use of tributylphosphine ligands in the CsPbBr 3 synthesis, 100% of PL QY has been achieved for CsPbI 3 QDs and CsPbBr 3 nanoplatelets .…”

“…For example, with the use of tributylphosphine ligands in the CsPbBr 3 synthesis, 100% of PL QY has been achieved for CsPbI 3 QDs and CsPbBr 3 nanoplatelets . Recently, the LSCs have already been fabricated by coating perovskite thin‐film on the glass, or embedding inorganic 3D CsPbX 3 (X = Cl, Br, I), mixed‐halide CsPb(Br x I 1‐x ) 3 , and doped CsPbCl 3 NCs in polymer matrix, while the current obtained external optical efficiency (η opt ) in single‐layer LSCs based on perovskite NCs is still low . Although Mn‐doped CsPbCl 3 perovskite NCs (or Yb 3+ ‐doped CsPbCl 3 ) can be as reabsorption‐free emitters, Meinardi et al highlighted that CsPbCl 3 ‐based perovskites are not suitable for the highly efficient large‐area LSCs due to both their relatively low PL QY (<15%) and their wide energy gap (only absorb sunlight less than 400 nm).…”

Luminescent solar concentrators (LSCs) are able to efficiently harvest solar energy through large-area photovoltaic windows, where fluorophores are delicately embedded. Among various types of fluorophores, all-inorganic perovskite nanocrystals (NCs) are emerging candidates as absorbers/emitters in LSCs due to their size/composition/dimensionality tunable optical properties and high photoluminescence quantum yield (PL QY). However, due to the large overlap between absorption and emission spectra, it is still challenging to fabricate high-efficiency LSCs. Intriguingly, zero-dimensional (0D) perovskites provide a number of features that meet the requirements for a potential LSC absorber, including i) small absorption/emission spectral overlap (Stokes shift up to 1.5 eV); ii) high PL QY (>95% for bulk crystal); iii) robust stability as a result of its large exciton binding energy; and iv) ease of synthesis. In this work, as a proof-of-concept experiment, Cs 4 PbBr 6 perovskite NCs are used to fabricate semi-transparent large-area LSCs. Cs 4 PbBr 6 perovskite film exhibits green emission with a high PL QY of ≈58% and a small absorption/emission spectral overlap. The optimized LSCs exhibit an external optical efficiency of as high as 2.4% and a power conversion efficiency of 1.8% (100 cm 2 ). These results indicate that 0D perovskite NCs are excellent candidates for high-efficiency LSCs compared to 3D perovskite NCs.

“…Thus, the absorption spectrum covers a large range of the UV region of the solar spectrum. It is perceivable based on these results that expanding the absorption range of organic–inorganic halide perovskites, through replacing the halogen atoms, and enhancing the Stokes shift can be used to further increase the efficiency of perovskite-doped luminescent solar concentrators. − …”

Organic−inorganic hybrid perovskites have attracted significant attention because of their distinguished optoelectronic properties, which can be applied in high-efficiency solar cells and light-emitting devices. A majority of the systematic studies on the regulation of the band gap in the family of organolead halide perovskites have focused on changing the compositions of halogens. However, mechanical compression provides a wider structural diversity without changing the composition. In this paper, fabrication of organic−inorganic hybrid perovskites (CH 3 NH 3 PbX 3 , X = Cl, Br, and I) is reported. The crystal structure, electronic properties, and optical band gap energies of the synthesized perovskites were investigated. Also, the effects of changing the external pressure on the band gap of CH 3 NH 3 PbX 3 , X = Cl, Br, and I were studied. The results indicate an important progress in tuning the band structure and optoelectronic properties of organometal halide perovskites via pressure engineering, which brings forward substantial implications for practical device applications. Investigation of the optical band transition induced through pressure could provide a different perspective on studying the perovskite materials.

“…Among the diverse classes of fluorophores, lead halide perovskite nanocrystals have great potential for application in LSC windows because of their impressive quantum yield (>90%), tunable band gap, and mass synthesis based on solution processes. − Along with their facile preparation and outstanding PL properties, printing of perovskite nanocrystal inks also yields large-area, transparent, and uniform luminescent films. Compositional engineering of the nanocrystals has also improved the Stoke shifts and PL reabsorption. ,− The resulting optical efficiency of over 5% proves that perovskite nanocrystals are highly suitable for LSC materials. − …”

Lead halide perovskite nanocrystals have emerged as core materials for next-generation optoelectronics because of their high quantum yield, tunable band gaps, and facile mass production based on solution processes. Conventional perovskite luminescent solar concentrators (LSCs) are prepared using nanocrystal/polymer composite films. They require a multistep fabrication process, including the presynthesis of nanocrystals and deposition of nanocrystal–polymer mixed solutions under controlled rheological parameters. Herein, we introduce highly efficient perovskite LSCs designed with electrospun perovskite/polymer composite nanofibers. Methylammonium lead bromide (MAPbBr3) nanocrystals were synthesized via a polymer-mediated in situ growth process during electrospinning. The annealing-free and one-step fabricated luminescent composite nanofiber mats exhibited excellent photoluminescence characteristics. The light absorption, transmittance, and optical haze of the nanofiber mats were further improved after poly(methyl methacrylate) (PMMA) layers were deposited. Nanofiber mats passivated with PMMA were used as an LSC film, exhibiting impressive optical efficiencies of 11.18% for geometry (G) factors of 2.77. The corresponding PCE of the Si solar cells coupled with LSC was 2.35%. This value was almost retained under continuous 1 sun illumination for 120 h. The LSCs also demonstrate their great potential in indoor environments, as they exhibit an excellent PCE of 5.3% under a white light illuminance of 1000 lx.
