“…With increasing concentration of Mn 2+ :CsPbCl 3 , the surface reflectance of the device on UV light significantly decreased, indicating that more UV light was absorbed and then converted (Figure 12e-h) to reach a higher PCE. This device obtained enhanced J SC (by 5.1%) and PCE (by 6.2%) compared to the original silicon device [122].…”

“…Ion doping is a promising strategy in adjusting the electronic and optical properties of QDs [120]. For HP-QDs, it was verified that introducing metal ions like Mn 2+ [121][122][123][124], Sn 2+ [121,125], Ce 3+ [126], Eu 3+ [127] into the perovskite lattice of CsPbX 3 QD could help reach tunable energy gap [123], enhanced thermal stability [121] and improved PL efficiency [126]. The fabrication strategies of ion doping contains hotinjection and melt-quenching.…”

“…For example, Sanehira et al adopted A-site cation halide salt (AX)-coated CsPbI 3 QDs where AX salt treatment could double the mobility, enhance the photocurrent and achieve highest PCE at 13.4% and short-circuit current density (J SC ) of 14.37 mA/cm 2 [171]. And in silicon solar cell (Figure 12a), the HP-QDs based composites could be used as luminescent downconverter layer [172], such as Mn 2+ :CsPbCl 3 [122,173]. The efficiency of the original silicon solar cell (Figure 12b) was low for short wavelength because of the undesirable parasitic optical absorption, which resulted in recombination loss and limited the device performance [174].…”

“…It is found that optimizing the efficiency of charge collection, reducing the charge recombination and promoting the separation of electronhole pairs are effective methods to improve the PCE of QDSSCs [17][18][19][20][21]. Moreover, expanding the light absorption range and enhancing the light absorption efficiency have significant effect on the PCE [22]. In fact, devices usually show moderate PCE in visible region [23], while the PCE in the ultraviolet and near-infrared regions are often limited [24].…”

Light absorption plays an important role in improving the power conversion efficiency (PCE) of quantum dot-sensitized solar cells (QDSSCs). In this study, a multifunctional long-persistence phosphor (LPP) layer was introduced into the CdS/CdSe QDSSCs via a simple doctor blade method. The LPP layer can simultaneously improve the light harvesting and photo charge transfer in CdS/CdSe QDSSCs. As a result, their short-circuit current and corresponding PCE are effectively enhanced. The PCE can reach up to 5.07%, which is about 24% larger than that of the conventional CdS/ CdSe QDSSCs without LPP layer. The solar cells can work in dark for a while due to the long-lasting fluorescence of the LPP layer. This research provides an effective way to improve the PCE of QDSSCs, and finds the possibility for all-weather QDSSCs.

radiation can lead to the overgrowth of perovskite quantum dots and the destruction of the surface structure. [7][8][9][10] Another major challenge for lead halide perovskites is the potential environmental hazard of lead element, which is not suitable for the sustainable development. Therefore, it is of great significance to explore nontoxic and stable perovskite alternatives.In lead-free perovskites, Sn (II)-based and Ge (II)-based perovskites are not satisfactory candidates for optoelectronic devices, because Sn 2+ and Ge 2+ are easily oxidized to Ge 4+ and Sn 4+ in the normal environment. [11,12] Another type of perovskite alternatives is to replace Pb with Sb or Bi, such as Cs 3 Sb 2 Br 9 and Cs 3 Bi 2 Br 9 . These perovskites have layered 2D structure, which limits their development in terms of stability and more efficient luminescence. [13][14][15] In recent years, the lead-free double perovskite structures (A 2 B″B″"X 6 ) with mixed cations (B" = B + , B″″ = B 3+ ) instead of B position has attracted extensive attention because of its high stability and low toxicity. [15][16][17][18][19] Double perovskite Cs 2 AgBiBr 6 and Cs 2 AgBiCl 6 have also been proposed. [20][21][22][23] At present, there are many kinds of cations can synthesize double perovskites. [24] In various double perovskite structures, Cs 2 AgInCl 6 has received the most attention because of its direct bandgap character, long carrier lifetimes, and easy solution processability. [25] The PLQY of Cs 2 AgInCl 6 is less than 0.1%, which is caused by parity-forbidden transitions. [26] Tang's group reported that adding Na + and a small amount of Bi 3+ ions into the Cs 2 AgInCl 6 lattice can change the symmetry of the crystal system, which can break the prohibition of parity-forbidden transitions and increase PLQY to 86%. [27] Furthermore, Xia and Yella's groups confirmed that the single-doped Bi element can improve the PLQY of Cs 2 AgInCl 6 . [28,29] Locardi et al. reported that the key to optimizing the luminescence of the Cs 2 AgInCl 6 nanocrystalline system lies in the partial substitution of Na + , resulting in an AgCl 6 energy level higher than the maximum value of valence band. Doping Bi 3+ causes the BiCl 6 energy level to be lower than the minimum value conduction band. [30] Our group found that the emission of Cs 2 AgInCl 6 can also be improved on structural adjustment by SiO 2 . Adding SiO 2 to Cs 2 AgInCl 6 changed Lead-free halide double perovskites continue to draw increasing attention in view of their nontoxicity and stability compared to lead-based perovskites. High-end full-color displays and white light illumination are based on blue-light excitation. However, the excitation of blue light of lead-free halide double perovskites Cs 2 AgInCl 6 at room temperature faces a great challenge, which is crucial to its commercial application. In this study, Cs 2 Ag 0.6 Na 0.4 In 0.8 Bi 0.2 Cl 6 /xKBr(KI), which can be excited under blue light, have been synthesized by solid-phase compression method. Under blue-light excitation, Cs 2 Ag 0.6 ...
