Problems solved by technology

Fluorescent waveguide light collection technology has similarities with traditional concentrating solar energy technology. They both gather light onto small-area photovoltaic cells to increase the power generation power of photovoltaic cells per unit area. Compared with it, it has many advantages, such as: the light concentrating method is not affected by the incident angle of sunlight, so it can absorb both direct light and scattered light, but the current fluorescent waveguide light collection technology still has obvious technical defects, such as : When light is irradiated on the surface of the fluorescent waveguide light-collecting layer, part of the light will be reflected. At the same time, due to the limited absorption spectrum range of the fluorescent material in the single-layer fluorescent waveguide, it can only absorb part of the spectrum, and some light will escape through reflection or refraction. Other spectra will pass through the fluorescent light waveguide, which will cause loss; for the fluorescence generated after the fluorescent material absorbs the spectrum, some of the fluorescent light will escape from the fluorescent light waveguide layer during the transmission process, resulting in energy loss; Under long-term irradiation, the temperature of the fluorescent light waveguide layer will increase, which will produce a certain thermal effect, thereby affecting the photoelectric conversion efficiency of the photovoltaic cell; the increase in device temperature will not only affect the normal operation of the photovoltaic cell, but also This part of the energy that produces the thermal effect will be wasted in vain, which will cause a loss of part of the energy.
