Boosting efficiency of luminescent solar concentrators using ultra-bright carbon dots with large Stokes shift

Abstract

Luminescent solar concentrators (LSCs) are able to collect large-area sunlight to generate electric power with a low cost, showing great potential in building-integrated photovoltaics. However, the low efficiency of large-area...

A Review of Perovskite Nanocrystal Applications in Luminescent Solar Concentrators

“…In addition, to improve PLQY and reduce the re‐absorption loss of luminophores, tandem strategies can be adopted to improve the utilization of escape and scatter light for achieving high light absorption efficiency. Carbon dots (C‐dots) are also promising and efficient emitters in LSCs, [ 100–105 ] Zhao et al. [ 99 ] proposed a tandem LSC based on C‐dots and perovskite QDs first.…”

Carbon dots (C-dots) are also promising and efficient emitters in LSCs, [100][101][102][103][104][105] Zhao et al [99] proposed a tandem LSC based on C-dots and perovskite QDs first. The implemented device layout of the LSC was shown in Figure 5d, in which the first layer was based on C-dots, the second layer was comprised of CsPb(Br 0.8 Cl 0.2 ) 3 QDs and the third layer was CsPb(Br 0.2 I 0.8 ) 3 .…”

Evolution and fabrication of carbon dot-based room temperature phosphorescence materials

“…In the last twenty years, the research on CDs has been widely carried out, and people have also reviewed and summarized their uorescence in various aspects, such as the classication, synthesis methods, uorescence regulation, uorescence mechanism, different precursor selection, and applications in various elds. 6,8,10,14,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] At the same time, the corresponding prospects for the uorescence development of CDs are also proposed. Although there are some reviews providing a brief introduction of the aerglow phenomenon (i.e., RTP and TADF) of CDs, [15][16][17][18][19][35][36][37][38] there are few articles specically describing the aerglow phenomenon related performance in detail.…”

Integration of Conjugated Copolymers‐Based Luminescent Solar Concentrators with Excellent Color Rendering and Organic Photovoltaics for Efficiently Converting Light to Electricity

“…[15] To overcome these obstacles, numerous efforts have been dedicated to LSCs, including (1) the employment of various fluorophores, such as organic dyes, [16][17][18] π-conjugated poly mers, [14,19] quantum dots, [20][21][22][23][24] and rare earth complexes. [25][26][27] The latest research results show that carbon dots (C-dots) with high quantum yields have a very good application prospect in the field of LSCs; [28][29][30][31] (2) optimizing transparent optical lightguide (usually glass or polymers). Poly (methyl methacrylate) (PMMA), [32] polycarbonate (PC), [33] and polydimethylsiloxane (PDMS) [34] are commonly used optical waveguide materials, and their refractive indices have an important influence on the total internal reflection of light; [35] (3) integrating LSCs with different types of photovoltaic devices.…”
