Abstract

Quantum-cutting luminescent solar concentrators (QC-LSCs) have great potential to serve as large-area solar windows. These QC nanocrystals can realize a photoluminescence quantum yield (PLQY) of as high as 200% with virtually zero self-absorption loss. Based on our previous work, we have constructed a Monte Carlo simulation model that is suitable to simulate the performance of the QC-LSCs, which can take into account the band-edge emissions and near-infrared emissions of the QC-materials. Under ideal PLQY conditions, CsPbClxBr3−x:Yb3+-based LSCs can reach 12% of the size-independent external quantum efficiency (ηext). Even if LSCs have a certain scattering factor, the CsPbClxBr3−x:Yb3+-based LSCs can still obtain an ηext exceeding 6% in the window size (>1 m2). The flux gain (FG) of the CsPbClxBr3−x:Yb3+-based LSC-PV system can reach 14 in the window size, which is a very encouraging result.

量子切割纳米晶体作为发光太阳能聚光器发光体的蒙特卡罗模拟

量子切割发光太阳能聚光器（QC-LSCs）在用作大面积太阳能窗口方面具有巨大潜力。这些 QC 纳米晶体可以实现高达 200% 的光致发光量子产率 (PLQY)，而且自吸收损耗几乎为零。在之前工作的基础上，我们构建了适合模拟 QC-LSC 性能的蒙特卡洛模拟模型，该模型可以考虑 QC 材料的带边发射和近红外发射。在理想的 PLQY 条件下，基于 CsPbClxBr3-x:Yb3+ 的 LSCs 可以达到与尺寸无关的外部量子效率（ηext）的 12%。即使 LSCs 具有一定的散射系数，基于 CsPbClxBr3-x:Yb3+ 的 LSCs 仍能在窗口尺寸（大于 1 m2）下获得超过 6% 的 ηext。在窗口尺寸下，基于 CsPbClxBr3-x:Yb3+ 的 LSC-PV 系统的通量增益（FG）可达到 14，这是一个非常令人鼓舞的结果。

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
