In this work, we detail two types of fabrication processes of four polymer optical fibers doped with lumogen dyes. The fiber preforms have been manufactured with two different methods: extrusion and casting. We have compared the performance of the two types of fibers as luminescent solar concentrators by calculating their optical efficiencies and concentration factors. The obtained results show better performance for those fibers manufactured by the casting process. We have also studied the photostability of the two types of fibers doped with the dye lumogen red under solar light radiation. A high thermal stability of the doped fibers has been observed.
在这项工作中，我们详细介绍了两种掺杂鲁米诺染料的聚合物光纤的制造工艺。光纤预制棒采用两种不同方法制造：挤出法和浇铸法。我们通过计算两种光纤作为发光太阳能聚光器的光学效率和聚光系数，比较了它们的性能。所得结果表明，通过浇铸工艺制造的光纤性能更好。我们还研究了两种掺杂鲁米诺红染料的光纤在太阳光辐射下的光稳定性。观察到掺杂光纤具有较高的热稳定性。
