Abstract
The invention discloses a paved solar photovoltaic power generation pavement module which sequentially comprises a substrate layer, a stress dispersion filling layer, a solar cell layer, a transparent protective layer and an anti-skid wear-resistant layer from bottom to top, wherein the solar cell layer comprises one or more solar cell pieces, the light transmittance of the transparent protective layer and the anti-skid wear-resistant layer is larger than or equal to 70%, the friction coefficient of the anti-skid wear-resistant layer is larger than or equal to 0.4, and the anti-skid wear-resistant layer comprises a base material layer and anti-skid particles attached to the upper surface of the base material layer. The paving type solar photovoltaic power generation pavement module disclosed by the invention enhances the strength and the friction force of the paving type solar photovoltaic power generation pavement module on the premise of ensuring the normal lighting of the solar cell, so that the paving type solar photovoltaic power generation pavement module is suitable for large-area popularization and application. In addition, the invention also discloses a manufacturing method and a paving method of the paving type solar photovoltaic power generation pavement module.
Description
Technical Field
The invention relates to the technical field of solar power generation, in particular to a paving type solar photovoltaic power generation pavement module and a manufacturing method and a paving method thereof.
Background
The solar photovoltaic power generation road surface capable of directly bearing traffic load is an exploratory leading-edge technology in the field of intelligent road surface engineering at present, and the technical difficulty lies in how to lay a power generation photovoltaic cell module on a road surface, and can bear vehicle rolling and avoid damage.
At present, the international solar photovoltaic power generation pavement technology has three major categories: a is similar to the brick block, hexagonal solar energy thick plate with concave and convex surface, fix on cement concrete foundation laid in advance with the rag bolt, the structural flatness of this kind of block is bad, it is apt to permeate water and easy to appear the basic unit and destroy, the solar energy thick plate is apt to deform and damage because of the surface course is excessive, in addition, it also has the defect that the fabrication cost is expensive and difficult to install; the other type is a solar photovoltaic power generation pavement structure which is formed by splicing precast cement concrete plates and is provided with solar cells and is paved with toughened glass, and the structure has the defects that the precast cement concrete plates are large in size and difficult to install on site, and the toughened glass has small surface friction and poor anti-skid property; the other structure is to cut the road surface pitch layer and form the installation department to bond, place or inlay the photovoltaic power generation subassembly on the installation department, because the pitch layer is higher to whole body nature requirement, appear the pitch layer after the cutting easily and become flexible, the displacement and sink the scheduling problem, thereby lead to the photovoltaic power generation subassembly to be destroyed.
Due to the defects, the existing solar photovoltaic power generation pavement technology is not suitable for large-area popularization and application.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the paving type solar photovoltaic power generation pavement module, which enhances the strength and the friction force of the paving type solar photovoltaic power generation pavement module on the premise of ensuring the normal lighting of the solar cell, is suitable for the driving of vehicles, can effectively reduce the impact on the solar cell piece by arranging the stress dispersion filling layer, prolongs the service life of the solar cell piece, and is suitable for large-area popularization and application.
