CN203038950U - Novel self-cleaning solar device - Google Patents

Abstract

The utility model relates to the technical field of solar energy, in particular to a novel self-cleaning solar energy device. It includes: an aluminum alloy frame arranged on both sides; inside the aluminum alloy frame, from top to bottom, there are respectively: an upper coating layer, a glass layer, a first EVA layer, a battery sheet layer, a second EVA layer and a bottom layer. The utility model applies a layer of special self-cleaning agent nano-coating on the surface of tempered glass to form a water film. When exposed to sunlight, fluorescent lamps or ultraviolet rays, the super-hydrophilic coating of the water film decomposes the dirt, and the dirt slides down together with the water film. Realize self-cleaning, making it difficult for dust or dirty liquids (including watery and even oily liquids) to adhere to the surface of the glass, or to be washed away by water (or rainwater) relatively easily, so that the glass surface is very easy to keep clean, reducing cleaning The trouble and labor cost of the glass surface saves time, effort and safety, and also saves the increasingly scarce water resources.

Description

A new self-cleaning solar device

technical field

The utility model relates to the technical field of solar energy, in particular to a novel self-cleaning solar energy device.

technical background

A solar power generation device is a device that directly converts solar energy into electrical energy through solar cell components. Solar cells are solid devices that realize P-V conversion due to the electronic characteristics of semiconductor materials. In the vast areas without power grids, such devices can conveniently realize lighting and life power for users. Developed countries can also be connected to the regional power grid. achieve complementarity. At present, from the perspective of civilian use, the "photovoltaic-building (lighting) integration" technology that has matured and has begun to be industrialized abroad is mainly researched and produced in China for small-scale solar power generation suitable for household lighting in areas without electricity. system; environmental protection and energy are issues of concern to the whole world.

The use of solar devices usually requires maintenance and maintenance. The trouble and labor costs of cleaning the glass surface greatly increase the cost and waste water resources. In the long run, it also affects its insulation performance, water resistance, and aging resistance; it needs to be improved.

Utility model content

The utility model provides a novel self-cleaning solar energy device with nanotechnology and self-cleaning functions.

In order to achieve the above object, the utility model adopts the following technical solutions:

A novel self-cleaning solar device comprising:

Aluminum alloy frames on both sides;

Inside the aluminum alloy frame, from top to bottom, there are respectively: an upper coating layer, a glass layer, a first EVA layer, a battery sheet layer, a second EVA layer and a bottom layer.

Preferably, the upper coating is a nano material coating on the glass layer.

Preferably, the glass layer is tempered glass.

Preferably, the bottom layer is a TPT backplane.

Preferably, the aluminum alloy frames on both sides of the solar device are fixed to the internal structure through solar sealing silicone.

Due to the adoption of the above scheme, the utility model applies a layer of special self-cleaning agent nano-coating on the surface of tempered glass to form a water film. Dirt slides down with the water film to achieve self-cleaning, making it difficult for dust or dirty liquids (including watery or even oily liquids) to adhere to the surface of the glass, or to be washed away by water (or rainwater) relatively easily, so that the glass surface is very easy Keeping it clean reduces the trouble and labor costs of cleaning the glass surface, saves time, effort and safety, and also saves the increasingly scarce water resources.
