Efficiency and ability to resist external electromagnetic interference. However, due to the fact that in actual use, as the incident light power continues to increase, the characteristics of the energy-transmitting optical fiber will change during long-term work, and the conversion efficiency of the photovoltaic effect at the receiving end will also be affected. influences
