Description

Solar photovoltaic power generation pavement

Technical field

The invention relates to a solar photovoltaic power generation road surface.

Background technique

The use of pavement solar photovoltaic cells to convert incident solar energy into electrical energy is an emerging hot spot in recent years. However, the fragile and smooth surface of the photovoltaic cell can not meet the requirements of road surface anti-sliding and pressure resistance. Therefore, paving a light-transmissive anti-sliding wear layer on the surface of a photovoltaic cell or its protective layer is the best technical route to solve the contradiction between traffic and power generation requirements. As solar photovoltaic power generation pavement technology research is still in its infancy, there are only three related cases in the world. One is a couple of scientists in Idaho, USA, Scott Brushaw and Julie. A solar photovoltaic cell is encapsulated by a hexagonal solar hollow slab having a concave-convex surface cast with high toughness glass. This concave-convex shape increases the bite of the vehicle tire and the road surface, but the surface lacks a fine texture, and under high-speed driving conditions, the friction is seriously insufficient, which is likely to cause a traffic accident. So, so far they have built a 15-square-meter open-air car park in Sandpoint, Idaho, USA. The second is the Dutch Solaroad company prefabricated 2.4 m × 3.3 m cement concrete slab, the surface is treated with tempered glass, in order to increase the friction, the glass is engraved with a lateral groove. However, this treatment also suffers from the lack of meticulous texture and does not provide the anti-sliding friction under high-speed driving. Therefore, only 230 feet (about 70 meters) is built in a town in the Netherlands called Cromoni. Solar bike pavement. The third is the French COLAS company directly sprays transparent packaging materials on the surface of solar photovoltaic panels. However, the surface not only lacks the necessary texture depth, but also has limited pressure bearing capacity, and it is easy to cause large-area photovoltaic panel breakage during use, which is difficult to be widely applied.
