Method for fabricating a light emitting module at a specific position of an illuminating solar cell

The present invention relates to a method of fabricating a solar cell, and more particularly to a method of fabricating a light emitting module at a specific location of an illuminating solar cell.

Building refers to a structure that is fixed to the ground and has the purpose of supporting and covering. Human beings provide various space for building or providing functional space for social operation. In other words, buildings generally have spaces where people can live and move.

In general, each building has at least one entrance and exit, appearing as a door or passage. A building can have one or several windows, or a window. Usually, the construction of buildings must focus on the interior design of the building and the appearance of the building. As people's environmental awareness of energy saving and carbon reduction rises, the combination of building and solar cells has become one of the research priorities, such as building integration. Building Integrated Photovoltaics (BIPV).

The building-integrated solar photovoltaic system is to develop a solar panel with building materials function, and then introduce the solar photovoltaic formwork building material into the building body by architectural design. In recent years, the industry has developed solar photovoltaic formwork glass with different solar transmittance as a window according to user requirements, and can simultaneously generate electricity and shade.

The invention provides a method for manufacturing a light-emitting module at a specific position of an illuminating solar cell, and a module for uniformly illuminating a light source from a solar panel can be easily fabricated.

The present invention provides a method for fabricating a light emitting module at a specific location of an illuminating solar cell, comprising fabricating a plurality of solar panels, and forming a small hole at a specific location on the front side of each solar panel. Then, a polymer gel is applied to the front surface of each solar cell panel, and then baked, and a plurality of convex portions are formed on each of the small holes. Thereafter, an LED light source is mounted on the side of each solar panel, and the light emitted from the LED light source can be uniformly illuminated from the front surface of each solar panel via the above-mentioned convex portion.

In an embodiment of the invention, the step of forming the small holes includes forming an array of small holes in the front side of each solar panel.

In an embodiment of the invention, the step of forming the small hole comprises forming a relatively small hole in a portion of the front surface of each solar panel that is close to the LED light source, and forming a portion of the front surface of each solar panel away from the LED light source. a denser hole.

In an embodiment of the invention, the solar panel comprises a transparent or opaque solar panel.

In an embodiment of the invention, the LED light source comprises a strip structure composed of a plurality of LED light emitting diodes.

Based on the above, the present invention can produce a illuminable solar panel for use on a building wall surface, and is designed with a module that can uniformly emit light, so that a building integrated solar photovoltaic system (BIPV) can be achieved, or a building can be designed according to requirements. Building Designed Photovoltaics (BDPV).

Referring to FIG. 1A, a solar panel 100 is fabricated. Although only a single solar panel 100 is shown, a plurality of solar panels 100 are actually required to be fabricated. Among them, the solar panel 100 includes a transparent or opaque solar panel, and the solar panel 100 generally includes a plurality of solar cells 102.

Thereafter, referring to FIG. 1B, a plurality of small holes 104 are formed at specific positions of the front surface 100a of each solar cell panel 100. For example, an array of small holes 104 may be formed in the front side 100a of each solar panel 100. As for how to form the small holes 104 in the front side 100a of the solar panel 100, laser hole punching, needle punching, or other suitable means may be employed.

Then, referring to FIG. 1C, a layer of polymer colloid 106 is applied to the front side 100a of the solar panel 100. The polymer colloid 106 is, for example, a packaging material for the solar panel 100 or other suitable polymeric material.

Next, referring to FIG. 1D, baking is performed to form a plurality of convex portions 108 on each of the small holes 104. The baking step herein is primarily to remove the solvent from the polymer colloid 106 while the polymer colloid 106 is automatically agglomerated into a raised portion 108 on the small hole 104.

Finally, referring to FIG. 1E, an LED light source 110 is mounted on the side 100b of each solar panel 100. The LED light source 110 includes a strip structure composed of a plurality of LED light emitting diodes 112. Therefore, when the LED light emitting diode 112 or the entire LED light source 110 is to be replaced, only the solar panel 100 is replaced, so the present invention has The advantage of convenient maintenance.

The light emitted from the LED light source 110 can be uniformly illuminated from the front surface 100a of each solar panel 100 via the raised portion 108 of the front side 100a of the solar panel 100, as shown in FIG. Such an illuminating solar cell composed of a solar panel 100 and an LED light source 108 is particularly suitable for illuminating at night.

In addition, the steps of FIG. 1B can also be formed as a thin hole 300a in a portion of the front surface 100a of each solar panel 100 that is close to the LED light source, and the front surface 100a of each solar panel 100 is away from the LED light source. The portion forms a denser hole 300b.

Referring to FIG. 4, the illuminating solar cell of the present invention can be applied to a building facade. The "building wall" herein refers to a wall 406 of the building 400 other than the window 402 and the entrance 404. As for the solar panel 100 having the lighting module of FIG. 1E, it can be laid on the wall 406 of the building 400, such as a residence, an office building, a school, a store, a gym, and the like.

In summary, the present invention can be used to fabricate illuminable solar panels on a building wall surface, and is designed with a module that can uniformly emit light, thereby making a solar panel with simultaneous power generation and uniform illumination, and used for construction.
