Embodiment 1

[0028] The invention provides a solar photovoltaic curtain wall, comprising an inner glass plate, an outer glass plate and a hollow cavity, the hollow cavity is arranged between the inner glass plate and the outer glass plate, the inner glass plate The glass plate and the outer wall of the outer glass plate are vacuum-coated, and the vacuum-coated film is calculated by weight percentage: 11.0% starch, 15.0% deionized water, 0.24% nano-silica powder, 0.18% Nano lanthanum oxide, 0.32% magnetic polystyrene nanospheres, 0.24% silica sol, and the rest are epoxy resin;

[0029] The invention also provides a preparation method of a solar photovoltaic curtain wall, and the specific preparation steps are as follows:

[0030] Step 1: Weigh starch, deionized water, nano-silica powder, nano-lanthanum oxide, magnetic polystyrene nanospheres, silica sol and epoxy resin according to the above weight percentages;

[0031] Step 2: The nano-silica powder in Step 1 is mixed with one-fifth of th...

Embodiment 2

[0041] The difference from Example 1 is that the thin film includes, by weight percentage: 17.0% starch, 19.0% deionized water, 0.36% nano-silica powder, 0.32% nano-lanthanum oxide, 0.50% magnetic polystyrene Nanospheres, 0.36% silica sol, and the rest are epoxy resins.

Embodiment 3

[0043] What is different from Examples 1-2 is that the thin film, calculated by weight percentage, includes: 14.0% starch, 17.0% deionized water, 0.30% nano silicon powder, 0.25% nano lanthanum oxide, 0.41% magnetic Polystyrene nanospheres, 0.30% silica sol, and the rest are epoxy resin.

[0044] Take the solar photovoltaic curtain wall prepared by above-mentioned embodiment 1-3 and the photovoltaic photovoltaic curtain wall of control group one, the photovoltaic photovoltaic curtain wall of control group two, the photovoltaic photovoltaic curtain wall of control group three, the photovoltaic photovoltaic curtain wall of control group four, and the control group respectively. The solar photovoltaic curtain wall of the fifth group and the photovoltaic photovoltaic curtain wall of the control group six were tested. The photovoltaic photovoltaic curtain wall of the control group 1 was an ordinary photovoltaic photovoltaic curtain wall on the market. Compared with the example, the ...

Abstract

The invention discloses a solar photoelectric curtain wall and a preparation method thereof, and specifically relates to the technical field of photoelectric curtain walls, including starch, deionized water, nano silicon powder, nano lanthanum oxide, magnetic polystyrene nano balls, silica sol and epoxy resin. In the present invention, starch is used as the second largest raw material except water in the raw material, and various substances in the raw material can be swollen, so that a large number of fine concave-convex surfaces are formed on the film-forming surface, and magnetic polystyrene nanospheres increase the concave-convex on the film-forming surface point; the gelatinized volume of starch becomes larger, and the volume of silica sol becomes smaller. The combination of the two can further improve the fine irregular structure of the film-forming surface, and the starch and epoxy resin can be modified to further improve the film-forming performance; Vacuum coating is prepared by different principles of layers, which can further strengthen the density of the fine concave-convex surface of the solar photovoltaic curtain wall, further improve the diffuse reflection effect, reduce light pollution, and ensure the safety of maintenance residents, pedestrians and vehicles.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic curtain walls, and more particularly, to a solar photovoltaic curtain wall and a preparation method thereof. Background technique [0002] Solar energy is an inexhaustible energy source. In order to convert solar energy into usable energy without pollution, photovoltaic curtain wall technology came into being. In addition to the performance of ordinary curtain wall, the biggest feature of photovoltaic curtain wall is the function of converting light energy into electrical energy. Photoelectric curtain wall, that is, pasted on glass and embedded between two pieces of glass, can convert light energy into electricity through batteries. Solar photovoltaic curtain wall uses photovoltaic cell and photovoltaic panel technology to convert sunlight into electrical energy. Its key technology is solar photovoltaic cell technology. Solar photovoltaic cells use the photon energy of sunlight to m...
