Low-reflectivity photovoltaic pavement
The invention relates to the technical field of solar energy application, in particular to a low-reflectivity photovoltaic pavement which comprises a concrete roadbed and a photovoltaic component fixedly covering the concrete roadbed. The photovoltaic component sequentially comprises a supporting base body provided with a groove, a photovoltaic assembly placed in the supporting base body and a light-transmitting surface layer arranged on the supporting base body and capable of covering the groove from bottom to top, the light-transmitting surface layer comprises concrete, a plurality of vertical through holes are formed in the concrete in a penetrating mode, and light guide elements are arranged in the vertical through holes. The light guide element is a polyetherimide-containing composition, and the light transmittance of the polyetherimide-containing composition is larger than or equal to 95%. The light-transmitting surface layer used by the road surface photovoltaic component selects the polyetherimide-containing composition as a light guide element, the light transmittance is high, the reflectivity is low, the situation that the sight of a driver is interfered by sunlight reflection can be effectively avoided, and therefore traffic accidents caused by the situation can be prevented.
本发明涉及太阳能应用技术领域，具体涉及一种低反射率光伏路面，包括混凝土路基和固定覆盖在混凝土路基上的光伏部件，光伏部件由下至上依次包括设有凹槽的支撑基体、放置在支撑基体内部的光伏组件和设置在支撑基体上并能够覆盖凹槽的透光面层，透光面层包括混凝土，混凝土上贯穿设置有若干竖直通孔，竖直通孔内设有导光元件，导光元件为含聚醚酰亚胺组合物，含聚醚酰亚胺组合物的透光率≥95%。本发明路面光伏部件所使用的透光面层选用含聚醚酰亚胺组合物作为导光元件，透光率高，反射率低，能够有效避免因太阳光反射干扰驾驶员视线的情况，从而预防因此造成的交通事故。
