Luminescent solar concentrators (LSCs) are considered a promising building‐integrated photovoltaic technology. Over the past decade, numerous luminophores have been developed for LSCs. However, conjugated polymers are rarely reported for LSCs despite their wide application in other fields. In this study, we investigated a luminescent conjugated polymer, poly(naphthalene‐alt‐vinylene) (PNV), for LSCs. PNV exhibits an absorption wavelength (λabs) of 535 nm, an emission wavelength (λem) of 632 nm and a photoluminescence quantum yield of 0.40 in a poly(methyl methacrylate) matrix. When tested under outdoor direct sunlight (1000 W m−2 ± 10%) and indoor diffuse light‐emitting diode (LED) light (10 W m−2 ± 10%), the PNV‐based LSCs with a size of 12 in. (30.48 cm) exhibited power conversion efficiencies (ηLSC) of up to 2.9% and 3.6%, respectively, and concentration ratios (C) of up to 1.49 and 3.53, respectively. The external quantum efficiencies of the LSCs and the edge emission spectra of the luminescent waveguides were analyzed to reveal the impact of surface scattering treatment on device performance. Monte Carlo ray‐tracing simulation was employed to project the performance of large‐area LSCs with sizes of up to 120 in. (304.8 cm). For the LSCs under outdoor direct sunlight and indoor diffuse LED light, the projected ηLSC values were 1.29% and 0.88%, respectively, and the projected C values were 6.73 and 8.62, respectively. This study suggests that high‐performance LSCs can be achieved through luminescent conjugated polymers. © 2021 Society of Chemical Industry

基于发光共轭聚合物的高性能混合发光散射太阳能聚光器
发光太阳能集中器（LSC）被认为是一种很有前途的建筑集成光伏技术。在过去的十年中，为LSC开发了许多发光体。然而，尽管共轭聚合物在其他领域得到了广泛的应用，但很少有关于LSC的报道。在这项研究中，我们调查发光共轭聚合物，聚（萘ALT -亚乙烯基）（PNV），为的LSCs。PNV表现出的吸收波长（λ ABS的535纳米，发射波长（）λ EM的632纳米）和聚（甲基丙烯酸甲酯）矩阵的0.40的光致发光量子产率。在室外直射阳光（1000 W m −2 ±10％）和室内漫射发光二极管（LED）灯（10 W m-2 ±10％）中，基于PNV-的LSCs与一个大小为12的。（30.48厘米）显示出的功率转换效率（η LSC最多分别为2.9％和3.6％，），并且浓度比（C ^向上的）分别为1.49和3.53。分析了LSC的外部量子效率和发光波导的边缘发射光谱，以揭示表面散射处理对器件性能的影响。使用蒙特卡洛光线追踪模拟来预测尺寸最大为120英寸（304.8厘米）的大面积LSC的性能。对于下室外阳光直射和室内漫射LED光的LSCs，投影η LSC值分别为1.29％和0.88％，和投影Ç值分别为6.73和8.62。这项研究表明，可以通过发光共轭聚合物实现高性能的LSC。©2021化工协会
