“…Here the thickness of the spectral downconverter is fixed at 3 mm. As Pr 3+ concentration increases from 2.6×10 26 ions/m 3 to 4.0×10 26 ions/m 3 , PCE and QCE decrease slightly, as shown in Fig. 3(a).…”

“…It should be pointed out that PCE and QCE (the total PCE and QCE) will no longer increase when the thickness exceeds the maximum (the optimal value), ascribed to absorption losses and side scatting losses within the spectral downconverter. 38 In our simulation, for a thickness of the spectral downconverter z = 3 mm, we obtain the optimal total PCE of 175% and the total QCE of 186% when optimal Pr 3+ and Yb 3+ concentrations are 1.7×10 25 ions/m 3 and 3.6×10 26 ions/m 3 , respectively.…”

Quantum cutting via a two-step resonant energy transfer in a spectral downconverter of Pr3+-Yb3+ codoped fluoride glass is investigated numerically by proposing up and solving the theoretical model of rate equations and power propagation equations. Based on the optimal Pr3+-Yb3+ concentration and the thickness of the spectral downconverter, the total power conversion efficiency of 175% and total quantum conversion efficiency of 186% are obtained. The performance of a sc-Si solar cell covered with a spectral downconverter is evaluated with the photovoltaic simulation programme PC1D. For sc-Si solar cells, the energy conversion efficiency of 14.90% for the modified AM1.5G compared to a 12.25% energy conversion efficiency for the standard AM1.5G has been obtained, and the simulated relative energy conversion efficiency for the sc-Si solar cell approaches up to 1.21. Our results show that the use of a spectral downconverter yields better sc-Si solar cell performance compared to the standard AM1.5G irradiation. The paper also provides a framework for investigating and optimizing the rare-earth doped spectral downconverter, potentially enabling a sc-Si solar cell with an efficiency improvement

“…For NIR emission, the NIR-sensitive R5509-72 PMT was employed accordingly, except that the normalization of the integrated intensity of the PL peak at 804 nm, recorded by R928 and R5509-72 PMTs, respectively, was first done to correct the relative sensitivity of the two different detectors. 28 Due to the limited spectral response of the R5509-72 PMT, the absolute QY of the 1800 nm PL band had to be evaluated via normalizing to the integrated intensity of the 1466 nm peak recorded with the PMT and the PbSe MIR detector. We expect significant experimental uncertainty for the quantitative analyses of the MIR data.…”

The construction of semiconductor nanocrystal (SNC)‐based composites is of fundamental importance for various applications, including telecommunication, lasers, photovoltaics, and spintronics. The major challenges are the intentional insertion of dopants into SNCs for expanding their intrinsic functionalities and the scalable incorporation of activated SNCs into host free of hydroxyl and organic species for stabilizing and integrating their performances. An in situ approach is presented to couple the SNC doping and loading processes through self‐limiting nanocrystallization of glassy phase, enabling one‐step construction of fully transparent Ga2O3 SNC–glass nanocomposites. It is shown that the intentional introduction of various cation/anion impurities (e.g., F−, In3+, and Ni2+) or their combinations into Ga2O3 SNCs can be realized by taking advantage of the viscous glass matrix to enhance the desorption barrier of impurity on the SNC surface and strengthen its tendency to incorporate into the SNC lattice. The composite can be rationally activated to show wavelength‐tunable and broadband luminescence covering the spectral ranges of near ultraviolet, visible, and near‐infrared wavebands. The approach is predicted to be general to other SNC materials for functional modulations and will be promising for scalable fabrication of novel SNC‐based composites.
