Monte-Carlo simulations of optical efficiency in luminescent solar concentrators based on all-inorganic perovskite quantum dots

Zero‐Dimensional Perovskite Nanocrystals for Efficient Luminescent Solar Concentrators

“…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).…”

High‐performance hybrid luminescent‐scattering solar concentrators based on a luminescent conjugated polymer

“…Our final task was to investigate the performance of large‐area (> 1000 cm 2 ) LSCs. To this end, we performed Monte Carlo ray‐tracing simulations to project the device performance 82–84 . Typical loss mechanisms were considered in the simulation, which were incomplete absorption of the incident light, luminophore self‐absorption, matrix absorption, internal scattering and surface scattering.…”

Carbon electrode engineering for high efficiency all-inorganic perovskite solar cells

“…Hybrid organic-inorganic perovskite materials, as potential candidates in the solar energy conversion, have drawn considerable attention owing to their broad absorption wavelength (up to $800 nm), strong absorption coefficient, high carrier mobility and facile processing techniques. [1][2][3][4][5][6] Since the rst report in 2009 with an initial power conversion efficiency (PCE) of 3.8%, 7 a rapid development of hybrid organic-inorganic perovskite solar cells (PSCs) and various robust deposition techniques, i.e., one-step/two-step solution strategy, 6,[8][9][10] vapor deposition [11][12][13][14][15] and vapor-assisted solution method, [16][17][18] have ensured a champion PCE of above 25.2% in the past decade. 19 However, the perovskite solar cells (PSCs) based on the hybrid counterparts such as methylammonium lead halide (MAPbX 3 ) and formamidinium lead halide (FAPbX 3 ) suffers from the inferior stability because of the decomposition of fragile cation materials under moisture and thermal attacks, which impede their commercial applications in the future.…”
