论文摘要
明显透明的发光太阳集合器（TLSC）可以通过选择性收获太阳光谱的无形部分来优化功率产生和可见透明度。由于TLSC的主要应用包括建筑信封，温室，汽车，标牌和移动电子设备，因此保持美学和功能与实践部署中的高功率转换效率（PCE）一样重要。在这项工作中，我们将大量降低的磷光纳米簇和荧光有机分子和荧光有机分子与TLSC系统相结合，分别为紫外线（UV）和近红外（NIR）选择性量的灯泡（NIR），分别与3％的uv和Nir Dual-Band选择的tlscs超过3％，分别表明UV和NIR双频体选择性（均为平均值）和适合窗户行业的颜色指标。对于TLSC系统，具有明显的波长选择性和有效利用太阳光谱的不可见部分，其最高光利用效率（PCE X AVT）为2.6，为TLSC系统，任何透明光伏设备的最高PCE，具有AVT大于70％的任何透明光伏设备，并且对非效率超过70％的限制，并超过了非波动长度的Photements Partyparents Partyparents Parteravel partparent partaveltafe partparents partparents。
Visibly transparent luminescent solar concentrators (TLSCs) can optimize both power production and visible transparency by selectively harvesting the invisible portion of the solar spectrum. Since the primary applications of TLSCs include building envelopes, greenhouses, automobiles, signage, and mobile electronics, maintaining aesthetics and functionalities is as important as achieving high power conversion efficiencies (PCEs) in practical deployment. In this work, we combine massive-downshifting phosphorescent nanoclusters and fluorescent organic molecules into a TLSC system as ultraviolet (UV) and near-infrared (NIR) selective-harvesting luminophores, respectively, demonstrating UV and NIR dual-band selective-harvesting TLSCs with PCE over 3%, average visible transmittance (AVT) exceeding 75% and color metrics suitable for the window industry. With distinct wavelength-selectivity and effective utilization of the invisible portion of the solar spectrum, this work reports the highest light utilization efficiency (PCE x AVT) of 2.6 for a TLSC system, the highest PCE of any transparent photovoltaic device with AVT greater than 70%, and outperforms the practical limit for non-wavelength-selective transparent photovoltaics.
