A Review of Perovskite Nanocrystal Applications in Luminescent Solar Concentrators

Abstract

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.

Strategies for the optimization of color neutral, transparent, and efficient luminescent solar concentrators

“…With the advent of mixed organic-inorgamic halide perovskites-based solar cell development, also perovskite QDs have been developed 56 for use in optoelectronics, including LSCs. [57][58][59] Perovskite QDs show wide spectral tunability 58 and can be easily solution processed.…”

Dimensional diversity (0D, 1D, 2D, and 3D) in perovskite solar cells: exploring the potential of mixed-dimensional integrations

“…There is a substantial body of literature, and we have come across a number of interesting review articles, each of which concentrated on a particular feature or characteristic of perovskite materials including 1D materials for efficient and stable PSCs, 75 solar cells with perovskite quantum dots, 5,76–79 nanocrystals in luminescent solar concentrators, 80 metal halide perovskite nano/microwires, 81 and metal halide perovskite nanorods. 82 There are still gaps in our understanding of the potential of perovskite solar cells because none of these articles provided a comprehensive analysis of the entire dimensional spectrum.…”

Organic A‐Site Cations Improve the Resilience of Inorganic Lead‐Halide Perovskite Nanocrystals to Surface Defect Formation

“…Lead halide perovskite (LHP) nanocrystals (NCs) have highly appealing properties for a variety of applications in next-generation optoelectronics. [1][2][3][4][5] These include narrow photoluminescence (PL) peaks, near-unity PL quantum yield (QY), long charge-carrier diffusion lengths, facile synthesis, and defect tolerance, among many others. These properties have made LHP NCs promising candidates for next-generation solar cells, light-emitting diodes (LEDs), quantum light sources, lasers, photodetectors, and photocatalysis.…”
