Luminescent solar concentrators (LSCs) are semitransparent windows that are able to generate electricity from sunlight absorption. LSCs have shown huge promise for realizing building-integrated photovoltaics (BIPV). Unfortunately, to date, the power conversion efficiency (PCE) of LSCs is still very low which dramatically hampers their practical applications. In this Perspective, We summarize and review the latest developments of LSCs by looking at different structures. Among others, we focus more on the next developments in the field of LSCs, i.e., the possibility of high PCE, large area, mass production, and durability needed for future industrial development. We hope to promote the application of uniform testing standards and to draw attention to industrial development, toxicity, and durability. Then, we will provide a critical assessment of the field of LSCs. Finally, the challenge and solution will be discussed.

Three types of halide-perovskite-based fast-acting fluorescent materials have been demonstrated for high-speed visible light communication. All-inorganic metal-halide perovskite CsPbI3 was utilized to generate red color at 685 nm, and twodimensional (2D) hybrid organic-inorganic halide perovskite nanosheets, (PEA)2PbI4 and (PEA)2PbBr4 (PEA= C8H9NH3), with peak photoluminescence (PL) wavelengths of 525 nm and 408 nm, were respectively used for green- and blue-light emission. The materials were then embedded in the polymethyl methacrylate (PMMA) to improve their durability and flexibility in practical applications. Pumped by a 405-nm violet laser, the red and green phosphors exhibit –3-dB modulation bandwidths of 14 MHz and 193 MHz, respectively. For the blue phosphor, a 124-MHz –3-dB bandwidth was obtained by using a 375-nm UVA laser diode. Benefitting from either the short PL lifetime or high PL quantum yield, aggregate Gb/s data transmission was achieved in the communication link. Direct current biased optical orthogonal frequency-division multiplexing (DCO-OFDM) modulation scheme was implemented with an adaptive quadrature amplitude modulation (QAM) signal. The transmission net data rates of RGB phosphors are 0.51 Gb/s, 0.93 Gb/s, and 0.43 Gb/s, respectively. The corresponding average bit error ratios are 3.5×10-3, 3.6×10-3, and 3.6×10-3, which are below the 7%-overhead forward error correction (FEC) criterion. Taking advantage of the tunability of the halide perovskite materials covering the whole visible range could further fulfill high-speed color-pure wavelength-division multiplexing by using a single source with multiple luminescent materials emitting light at different wavelengths. Besides, combining luminescent materials with specific colors, simultaneous white-light illumination, and high-speed communication can also be realized.

“…All-inorganic CsPbX 3 (X = Br, Cl, and I) perovskite quantum dots (PQDs) have emerged as next-generation materials for developing high-performance photonic and optoelectronic devices such as, photodetectors, [1][2][3] light-emitting diodes (LEDs), [4][5][6][7] lasers, [8][9][10][11] photovoltaics (PVs) [12][13][14] and luminescent solar concentrators. [15][16][17] Tunable bandgap, narrow emission bandwidth, near unity photoluminescence quantum yield (PLQY), high charge carrier mobility, and large photon absorption are intriguing features of metal halide perovskites that are the main reasons behind their popularity in recent years. 18 However, their lingering drawbacks of poor thermal, chemical, and photo-stability along with toxic element (such as Pb) dependency keep them away from most of the practical applications.…”
