Description
The present invention relates to an amorphous thin film solar cell module, and more particularly, to a transmissive amorphous thin film solar cell multilayer module.
Recently, research and product development for the application of the photovoltaic power generation system in the field of construction have been actively conducted.
If the solar cell module used as a building material is installed in the building in the form of a junction module without multilayering, condensation occurs due to temperature difference inside and outside. In order to prevent this, the solar cell junction module is made of a double layer module by adding an air layer (6 mm or 12 mm) to the solar cell bonding module so that the heat transmission rate is usually 2.6 to 2.7 W / ㎡ ℃ value.
An example of a conventional transmissive amorphous thin film solar cell multilayer module has a structure as shown in FIG. 1, and a method of manufacturing the transmissive thin film amorphous solar cell including a transparent conductive film glass (TCO glass) and an amorphous thin film deposited on glass ( 11), the EVA sheet (Ethyl Vinyl Acetate sheet) 12 and the front float glass (13) are sequentially bonded (laminated) to form a transmissive amorphous solar
At this time, the transfer rate of the temperature applied to the
In addition, the
The present invention is excellent in bonding to the EVA sheet, the heat transfer rate applied to the transmissive amorphous thin film solar cell bonding module is fast, the curing reaction rate of the EVA sheet is a transmissive amorphous thin film that can improve the production efficiency Provides a solar cell multilayer module.
The present invention also provides a transmissive amorphous thin film solar cell multilayer module that is lighter than a conventional transmissive amorphous thin film solar cell multilayer module and is easy to install and install.
A transmissive amorphous thin film solar cell multilayer module according to an embodiment of the present invention is a transmissive thin film solar cell including a transparent conductive film glass and an amorphous thin film deposited on the transparent conductive film glass, an EVA sheet bonded to the amorphous thin film And a front transparent plastic film bonded to the EVA sheet, an aluminum spacer bonded to the transparent plastic film and having an air layer, and a rear transparent plastic film or rear float glass bonded to the aluminum spacer.
That is, the present invention is a form of a multi-layered structure including a transmissive amorphous thin-film solar cell bonding module consisting of a transmissive thin film solar cell, an EVA sheet, and a front transparent plastic film, an aluminum spacer having an air layer, and a rear transparent plastic film or a rear float glass. The multi-layer module can be configured.
Accordingly, the present invention can significantly reduce the weight of the entire transmissive amorphous thin film solar cell multilayer module by replacing the conventional front float glass with a transparent plastic film having a lower density than glass. The amorphous thin-film solar cell multilayer module of the present invention having such a structure can reduce the weight of the module itself by about 35%, thereby improving the workability when handling the module and installing it in a building, and as the overall thickness of the multilayer module becomes thinner. It is advantageous to design aluminum frame for installation in building and has the advantage that existing general purpose aluminum frame can be used as it is.
In the transmissive amorphous thin-film solar cell multilayer module according to the exemplary embodiment of the present invention, the heat shrinkage rate of the front transparent plastic film or the rear transparent plastic film for 20 minutes in a 150 ° C. hot air is 3% or less.
That is, the transparent plastic film of the present invention needs to be excellent in dimensional stability even at high temperature, but when the heat shrinkage is 3% or less, or preferably 1% or less when left in a hot air at 150 ° C. for 20 minutes, it is a transmissive amorphous solar cell. The bonding module may not be affected by shrinkage in the process of bonding the transparent plastic film to the EVA sheet carried out below 150 ℃ during the manufacturing process. In addition, when the transmissive amorphous thin film solar cell multilayer module of the present invention is constructed and used, it can be prevented from being deformed even under a high temperature environment.
In addition, according to the present invention it is possible to facilitate the temperature transfer to the EVA sheet, it is possible to speed up the curing reaction of the EVA sheet in the manufacture of the transmission-type amorphous thin-film solar cell multilayer module of the present invention.
In addition, since the transparent plastic film in the present invention is provided on the back side of the transmissive thin film solar cell, the influence of power generation performance by the transmittance of the transparent plastic film itself is not affected. In addition, when the visible light transmittance of 80% or more, the sunlight transmitted through the transmission type thin film battery cell can be transmitted through the room well. In particular, it is preferable that visible light transmittance is 90% or more.
In the transmissive amorphous thin film solar cell multilayer module according to the exemplary embodiment of the present invention, the front transparent plastic film or the rear transparent plastic film may be a polyester film, and the polyester film may have a thickness of 200 μm or more.
That is, it is preferable that the transparent plastic film in this invention is a polyester film. Polyester film is a representative transparent plastic film excellent in various basic physical properties, has a particularly strong strength and moderate elongation, in particular, has excellent optical properties. In particular, it is preferable that the thickness of the polyester film in this invention is 200-350 micrometers. That is, in order to ensure further excellent mechanical strength, it is preferable that it is 200 micrometers or more, and in order to make heat transfer to EVA film smooth, it is preferable that it is 350 micrometers or less.
The polyester film in the present invention may be a polyethylene terephthalate film, a polybutylene terephthalate film, a polyethylene naphthalate film, or the like.
As a result, the present invention provides a transmissive amorphous thin-film solar cell multilayer module that can increase the ease of a bonding operation process for manufacturing a transmissive amorphous thin-film solar cell bonding module and easily control the reaction rate of the EVA sheet.
In addition, as the weight of the transmissive amorphous thin-film solar cell multilayer module is reduced and the thickness is also thin, the constructability can be improved in the design of the frame or the application of the building.
