Description

Programmable luminous vertical solar cell

This invention relates to a solar cell, and more particularly to a vertical strip solar cell that can be programmed to emit light.

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 vertical light-emitting solar cell capable of stylized illumination, which can simultaneously have the functions of power generation and illumination, and can also be designed with a wall surface.

The invention provides a vertical light-emitting solar cell capable of stylizing illumination, comprising a plurality of vertical strip solar panels and an LED light source. The vertical strip solar panel is disposed on a plurality of walls of a building, wherein the vertical strip solar panel comprises a plurality of vertical strip solar cells. The LED light source is disposed on the side of each of the vertical strips of solar panels, so that each of the vertical strips of solar panels emits different colors of light, and converts sunlight into electrical energy by emitting colored solar cells of different colors. And the electric energy is used to make the LED light source emit light.

In an embodiment of the invention, the vertical strip solar cell comprises a twinned solar cell.

In an embodiment of the invention, the LED light source comprises a strip structure composed of a plurality of LEDs of different colors of LEDs.

In an embodiment of the invention, the LED light source comprises red, green and blue LED light emitting diodes.

In an embodiment of the invention, the building comprises a house, an office building, a school, a store or a gym.

Based on the above, the present invention uses a programmable light-emitting vertical solar cell on a building wall surface to achieve a building integrated solar photovoltaic system (BIPV), or a simple pattern on the wall of a building designed according to requirements, thereby making the building The wall of the object has the function of notice.

The above described features and advantages of the present invention will be more apparent from the following description.

1 is a schematic illustration of a programmable light-emitting vertical solar cell applied to a building facade in accordance with an embodiment of the present invention.

Referring to FIG. 1, the "building wall surface" in the present embodiment refers to a wall surface 106 of the building 100 other than the window 102 and the entrance and exit 104. As for the programmable light-emitting vertical strip solar cell applied to the building wall of the present invention, the vertical strip-shaped solar panel 108 and the LED light source 110 are included. Vertical strips of solar panels 108 are disposed on the wall 106 of the building 100, wherein the vertical strips of solar panels 108 can emit colored lights of different colors. A simple pattern can be created on the wall 106 of the building 100 by selectively illuminating the vertical strips of solar panels 108 on different areas of the wall 106. For example, a cartoon pattern, a number or a text, etc., in turn, causes the wall 106 of the building 100 to have a function of notice.

The above-described building 100 is, for example, a house, an office building, a school, a store, a gym, and the like. The vertical strip solar panel 108 generally includes a plurality of vertical strip solar cells 200, as shown in FIG. Among them, the vertical strip solar cell 112 is, for example, a twinned solar cell or a transparent solar cell. The LED light source 110 is disposed on the side surface 108a of each of the vertical strip-shaped solar panels 108 so that each vertical strip-shaped solar panel 108 emits light, and the solar energy of the vertical strip-shaped solar cell 200 is converted into electric energy, and at the same time The generated electric energy can be transmitted to the LED light source 110 for illumination.

In the embodiment, the LED light source 110 includes a strip structure composed of a plurality of different color LED light emitting diodes 300. As shown in FIG. 3, the LED light source 110 may include a red LED light emitting diode DR, a green light emitting diode DG, and a blue LED light emitting diode DB, but the practical application is not limited thereto. Therefore, when the LED light-emitting diode 300 or the entire LED light source 110 is to be replaced, it is only necessary to replace it from the outside of the vertical strip-shaped solar cell panel 108, so that the present invention has the advantage of convenient maintenance. When the LED light source 110 emits light, the light can be reflected by the bottom surface 108b of the vertical strip solar panel 108, as shown in FIG. The LED light source 110 emits light of different colors by driving the LED light-emitting diodes of different color lights in the LED light source 110. Such a staggerable vertical solar cell consisting of a vertical strip of solar panel 108 and an LED light source 110 is particularly suitable for illumination at night.

In summary, the present invention provides a programmable light-emitting vertical solar cell on a building wall surface, so that it can simultaneously have the functions of power generation and light emission, and is used for a building integrated solar photovoltaic system (BIPV). By selectively illuminating the vertical strips of solar panels on different areas of the wall, a simple pattern can be created on the walls of the building, giving the building's walls a noticeable function.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
