Description

A window type solar photovoltaic module

technical field

The utility model relates to a solar photovoltaic assembly, in particular to a window-type solar photovoltaic assembly, which belongs to the technical field of solar energy.

Background technique

With the increasing global energy crisis, environmental problems, population growth and land problems, people's demand for new energy, especially clean and non-polluting renewable energy is becoming more and more urgent. As a clean renewable new energy, solar energy has received more and more attention in recent years, and its application has become more and more extensive. At present, photovoltaic power generation technology has been applied on a large scale. The most basic unit of solar photovoltaic power generation is a solar cell, which is a semiconductor device that directly converts light energy into electrical energy.

In the actual application of photovoltaic power generation, a plurality of solar cells are usually assembled in series and parallel to form a solar cell module, and then a plurality of solar cell modules are connected to form an overall current output. At present, solar cell components have been widely used in photovoltaic power plants, roof photovoltaic systems, curtain wall photovoltaic systems and lighting systems, but solar cell components are rarely used on windows of ordinary buildings. The main reason is that the general solar component structure cannot It is well matched with the window, which makes installation difficult; in addition, most of the components use an opaque back panel, which cannot guarantee the light transmission function of the window.

Utility model content

The technical problem to be solved by the utility model is to provide a window-type solar photovoltaic module, which can be easily installed in the window frame of the building, and can move freely in the slot of the window, which ensures the transparency of the window. Light, but also has the function of power generation, while saving space, can be widely used in doors and windows of buildings and other occasions.

The technical solution for realizing the utility model is: a window-type solar photovoltaic module, including a tempered glass layer arranged in a frame from top to bottom, a first EVA (ie, ethylene-vinyl acetate copolymer) layer, a solar cell Layer, the second EVA layer and the back plate, the outer sides of the two short sides of the frame are respectively provided with grooves. This design enables the components to be conveniently fixed in the card slot of the window and move freely in the card slot.

The back plate can be made of toughened glass or transparent TPT material or PET material, so that the component has a certain degree of light transmission.

The frame can be made of aluminum alloy or high-strength plastic.

Compared with the prior art, the utility model has the following advantages: (1) Since the back plate adopts high-transmittance toughened glass or transparent back plate, the light transmission performance of the module is guaranteed to be good; (2) The groove structure of the frame of the module can be well It matches the ordinary window structure and is easy to install; in addition, the components can move freely in the slot of the window, so it can ventilate the room like opening an ordinary window; (3) The components are directly installed on the windows, saving the cost of separate installation of components The space saves window materials; (4) The components not only have good heat insulation and sound insulation effects, but also have good sealing performance of the windows, and can also supply power to the building at the same time.

Detailed ways:

Below in conjunction with accompanying drawing, the technical characterictic of the present utility model and content are described further.

Referring to Figure 1, a window-type solar photovoltaic module includes a tempered glass layer 1, a first EVA layer 2, a solar cell layer 3, a second EVA layer 4 and a back sheet arranged in a frame 6 from top to bottom 5. The above-mentioned parts are laminated at high temperature to form a whole, and finally the frame is installed and formed. The outer sides of the two short sides 61 of the frame 6 are respectively provided with grooves 61a. The groove 61a can be well matched with the upper and lower slot structures of ordinary windows, and the whole assembly can move freely in the window frame along the slot, so the window-type solar photovoltaic module has the function of a general window, and it also has Power generation function, which can supply electricity to buildings. Since the assembly is formed by high-temperature lamination of multiple layers of components, it provides better thermal and acoustic insulation than normal windows, and the window's airtightness is enhanced.

The back plate 5 is made of toughened glass or transparent TPT material or PET material, so that the component has a certain degree of light transmission. The frame 6 is made of aluminum alloy or high-strength plastic.

The process steps for preparing the above-mentioned window-type solar photovoltaic module are as follows: first place a piece of ultra-white low-iron tempered glass on the laying workbench, lay a layer of EVA on it, and spread the solar cells welded in series on the above-mentioned EVA, and then Spread a layer of EVA on the solar cells, and finally lay a back sheet on the top layer. Put the paving piece into a vacuum laminator for high-temperature lamination, so that the EVA in it can be cured at high temperature to form a whole laminated piece. Then frame the trimmed laminate, and install a frame with a groove structure on the short side to obtain a window-type solar photovoltaic module.

In this embodiment, the solar cells in the module can be adjusted according to the light transmittance requirements of the window. By adjusting the number of solar cells and the distance between the solar cells, different light transmittances of the windows can be ensured.
