Description

A photovoltaic module with interior decoration effect

technical field

The utility model relates to the technical field of solar photovoltaic components, in particular to a photovoltaic component with interior decoration effect used in photovoltaic building integration.

Background technique

Photovoltaic modules, commonly known as solar panels, are devices used to convert the energy of photons into electrical energy. Ordinary photovoltaic modules generally include front and rear layers of encapsulation materials and multiple battery sheets and adhesive layers arranged between the encapsulation materials. Each battery sheet is connected to each other through battery lead wires and connected to the lead wire of the module. . Photovoltaic modules are used in systems such as curtain walls, daylighting roofs, awnings, and canopies, which is Building Integrated Photovoltaics (BIPV). Because of the batteries installed between the glass, the glass that could be used for lighting or observation is interrupted by multiple groups of batteries, forming a monotonous pattern of strips or blocks, alternating light and dark, which affects its visual effect , limiting its scope of use.

Utility model content

The purpose of this utility model is to provide a photovoltaic module with an interior decoration effect to expand the application range of the photovoltaic module and enhance the visual effect.

The technical scheme of the utility model is as follows:

A photovoltaic module with an interior decoration effect, comprising an outer layer of glass as an outer layer of encapsulation material and an inner layer of glass as an inner layer of encapsulation material, and a plurality of battery sheets are arranged between the outer layer of glass and the inner layer of glass, The plurality of battery sheets are connected to each other through wires to form a battery sheet group, and the battery sheet group is connected to the lead wire of the module, wherein: the inner glass is coated with a coating with a decorative pattern.

Further, an adhesive layer is filled between the two sides of the battery sheet and the outer glass and the inner glass respectively.

Further, the coating with decorative patterns is a baking varnish layer or a colored glaze layer.

The beneficial effects of the utility model are: the photovoltaic module with interior decoration effect provided by the utility model, since the coating with a decorative pattern is coated on the inner glass of the photovoltaic module, under the irradiation of sunlight, the photovoltaic module The module presents a specific decorative pattern effect, which avoids or weakens the monotonous visual effect of light and dark due to the cells blocking sunlight, achieves the purpose of interior decoration and expands the scope of application.

Detailed ways

The utility model provides a photovoltaic module with interior decoration effect. In order to make the purpose, technical solution and advantages of the utility model clearer and clearer, the utility model will be further described in detail below with reference to the accompanying drawings and examples.

The photovoltaic module with internal decoration effect provided by Embodiment 1 of the present utility model, as shown in Fig. A layer of glass 102, between the outer layer of glass 101 and the inner layer of glass 102, a battery sheet 103 group is arranged, and the battery sheet 103 is connected to each other through wires, and the battery sheet group is connected to the lead wire of the photovoltaic module. A glue layer 104 is filled between the glass 101 and the inner glass 102. The inner glass 102 is coated with a decorative pattern coating 105, so that the inner glass 102 is a craft glass with a decorative pattern coating 105.

In the first embodiment, the outer glass 101 must be glass with good light transmission performance, so that sunlight can penetrate and irradiate the battery sheet 103 , so that the battery sheet 103 absorbs more light energy. At present, there are many glasses with excellent light transmission properties to choose from. In the first embodiment, tempered ultra-clear glass is preferred as the outer glass 101 . The main reason is that in building integrated photovoltaics, photovoltaic modules as building components are generally installed outside the building as the outer wall or roof of the building, not only to withstand the test of wind, sun and rain, but sometimes may Need to bear a certain pressure, tempered ultra-clear glass not only has excellent light transmission performance, but also has a certain bearing capacity.

In this embodiment one, the process glass with a decorative pattern coating is used as the inner layer glass 102. The main selection is based on the following reasons. Light transmission performance, when the photovoltaic module is used as the wall of the building, the inner glass 102 needs to have a certain decorative effect to be recognized by the market. Therefore, the inner glass 102 in the first embodiment is preferably colored glaze glass or painted glass. The inner glass 102 is coated with a colored glaze layer or a baked varnish layer as a coating with a decorative pattern. It can be kept for a long time due to the coating of colored glaze patterns or baking varnish patterns on the glass. Moreover, when the photovoltaic module of the first embodiment is used as the outer wall or roof of a building, since the colored glaze or painted glass is used as the inner packaging material of the photovoltaic module, the colored glaze or painted glass has and presents spots The pattern, viewed from the indoor surface, avoids the monotonous light and dark pattern caused by the battery sheet 103, and replaces it with decorative colored glaze or baked varnish spot pattern. The colored glaze pattern or baking varnish pattern can be in dot shape, strip shape, arc shape or other regular shapes. Or the regular combination of various shapes adds to the richness of decorative patterns and meets the needs of different decorative effects.

The photovoltaic module with internal decoration effect provided by the second embodiment of the utility model is shown in Fig. The layer 205 presents landscape paintings or other decorative patterns, which have a good interior decoration effect. The photovoltaic module also includes: an outer layer glass 201 as an outer layer encapsulation material and an inner layer glass 202 as an inner layer encapsulation material, and a battery sheet 203 group is arranged between the outer layer glass 201 and the inner layer glass 202, and the battery sheet 203 is passed through a wire The cells are connected to each other, the cell group is connected to the lead wires of the photovoltaic module, and glue layers 204 are filled between the two sides of the cells 203 and the outer glass 201 and the inner glass 202 respectively. The inner glass 202 is coated with a decorative pattern coating 205 , so that the inner glass 202 is a process glass with a decorative pattern coating 205 .

Using the photovoltaic module of the second embodiment in a building can avoid the monotonous pattern of stripes or blocks with alternating light and dark and the impact on the visual effect due to the use of other photovoltaic modules. The glazed glass or painted glass on the inner surface can provide landscape paintings or other decorative patterns, or special patterns required by users, which improves the effect of interior decoration and meets the requirements of users for interior decoration. Especially suitable for office buildings, high-end residential buildings, high-end hotels, hotels and other buildings.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation.
