Review on Colloidal Quantum Dots Luminescent Solar Concentrators

Abstract

Luminescent solar concentrators (LSCs) have recently gained popularity as an effective solution to increase solar energy conversion. Utilizing LSCs together with solar cells can generate more energy at a lower cost than using only solar cells. LSCs operate by utilizing luminophores, molecules that absorb incident solar irradiation and re‐emit photons, and waveguides that redirect emitted photons to the edges of a glass or polymer slab at high concentrations. Many quantum dots (QDs) have been the focus of much research as luminophores for LSCs, owing to their high quantum yields (QYs), controllable absorption/emission spectra, good stability, and ease of synthesis. Various QDs, such as CdSe, PbS, CdS, AgInS2, Si, and C, have been modified to enhance their optical performances in LSCs, often measured by their optical efficiencies, internal/external quantum efficiencies, and power conversion efficiencies. This review appraises the latest developments in colloidal QDs—basic QDs, doped QDs, core/shell QDs, hybrid QDs, and Si‐based QD—for their applications in LSCs. Other factors that enhance an LSC's efficiency, such as altering the polymer matrix and using distributed Bragg reflectors, are discussed. The development of highly efficient, QD‐based LSCs will be essential for increasing solar energy production worldwide.

“…12 }-Y@PVP Films PVP is the second example of matrixes used in these works, and it is often a good candidate complementary to the SiO 2 -PEG matrix. Indeed, the PVP is a nontoxic, biodegradable and biocompatible polymer with an interesting temperature resistance and pH stability, recently used for energy and optical applications [11,12,14,30,32,33,[39][40][41][42][43][44][45][46][47]. These results, especially thus on thin films, have shown that it is clearly possible to incorporate inorganic nanoparticles or nanoclusters directly at high concentrations into a PVP matrix without observing any segregation between the organic and inorganic phases.…”

“…By contrast, quantum dots and quantum rods have been intensively studied for applications such as LCDs, 25 micro-LED displays, 26 and LSCs. 27 Their narrow emission spectra result in a larger color gamut for display applications. Large Stroke's shift mitigates the photon loss due to selfabsorption in LSCs.…”

“… 42 − 46 QDs exhibit a narrow, tunable, and symmetric emission spectrum compared to organic fluorophores. 47 , 48 However, QDs with small capping agents tend to aggregate or agglomerate. Thus, large molecules such as biopolymers can be used as stabilizers and capping agents for QDs.…”
