The results are presented for luminescent solar concentrators (LSCs) fabricated with poly(lauryl methacrylate-co-ethylene glycol dimethacrylate) (P(LMA-co-EGDMA)) and Angstrom Bond, Inc. AB9093 acrylic epoxy matrix, high quantum yield (> 70%) PbSe quantum dots (QDs) and silicon photovoltaic (Si PV) cells. LSCs were tested under a lamp with broadband illumination, photon flux-matched to a standard solar spectrum and verified under a calibrated solar lamp source. The P(LMA-co-EGDMA) sample demonstrated the highest power conversion efficiency of any known LSC fabricated with either QDs or Si PV cells, 4.74%. Additionally, increased temperature was shown to reduce efficiency.
研究结果表明，采用聚（甲基丙烯酸月桂酯-乙二醇二甲基丙烯酸酯）（P（LMA-co-EGDMA））和 Angstrom Bond，Inc. AB9093 丙烯酸酯环氧树脂基质、高荧光量子产率（>70%）PbSe 量子点（QDs）和硅光伏（Si PV）电池制备的发光太阳能集中器（LSCs）。在与标准太阳光谱相匹配的宽带照明灯下测试了 LSCs，并在经过校准的太阳能灯源下进行了验证。与使用 QDs 或 Si PV 电池制造的任何已知 LSC 相比，P（LMA-co-EGDMA）样品表现出最高的功率转换效率，为 4.74%。此外，研究表明，温度升高会降低效率。
