Abstract The use of luminescent solar concentrators (LSCs) is considered a promising solution for harvesting indoor and outdoor light energy. Despite a multitude of investigations of LSC based photovoltaic (PV) systems, few reports are available on LSCs for emerging PVs, such as third-generation PV technologies. To fill this gap, we develop a novel LSC based PV device by coupling an LSC with a low-cost organic solar cell. The LSC is fabricated by employing different concentrations of organic luminophores, while a polymer/fullerene-based photoactive layer is prepared for the organic PV (OPV) device. With proper spectral matching, our champion LSC-OPV device exhibits optical efficiency (ηopt) and power conversion efficiency (ηPCE) of 6.10% and 0.51% under light-emitting diode (LED) illumination, respectively. Further, performance evaluation under 1sun illumination implies the ηopt and ηPCE of 8.5% and 0.17%. We also perform the color analysis of LSC-OPV devices which shows that such devices are aesthetically feasible for use in indoor and outdoor conditions. Thus, this study highlights the substantial opportunity for the rational design of hybrid LSC-PV systems where third-generation PVs are viable prospects.

通过将低成本有机太阳能电池与发光太阳能聚光器耦合来收集室内/室外光

摘要 使用发光太阳能聚光器 (LSC) 被认为是收集室内和室外光能的有前途的解决方案。尽管对基于 LSC 的光伏 (PV) 系统进行了大量调查，但关于用于新兴 PV（例如第三代光伏技术）的 LSC 的报告很少。为了填补这一空白，我们通过将 LSC 与低成本有机太阳能电池耦合，开发了一种基于 LSC 的新型光伏器件。LSC 是通过使用不同浓度的有机发光体制造的，同时为有机 PV (OPV) 器件制备了基于聚合物/富勒烯的光敏层。通过适当的光谱匹配，我们的冠军 LSC-OPV 器件在发光二极管 (LED) 照明下的光学效率 (ηopt) 和功率转换效率 (ηPCE) 分别为 6.10% 和 0.51%。更多，1sun 光照下的性能评估意味着 ηopt 和 ηPCE 分别为 8.5% 和 0.17%。我们还对 LSC-OPV 设备进行了颜色分析，这表明此类设备在室内和室外条件下都具有美学可行性。因此，本研究强调了合理设计混合 LSC-PV 系统的重大机会，其中第三代光伏是可行的前景。
