Description

Technical Field

[0001] The present invention relates to a photovoltaic module, and more particularly to a perovskite photovoltaic module and a building shading device including the perovskite photovoltaic module.

Background Art

[0002] With the development of renewable energy technologies, a solar power generation system has become one of the important means to solve energy problems. Conventional solar power generation systems mainly consist of independent solar panels, and these solar panels are generally installed on rooftops or other open spaces to convert sunlight into electrical energy. However, this design is subject to limitations such as occupying space, high installation costs, and affecting the appearance of buildings.

[0003] As related technologies progress, solar windows have emerged. These windows can not only provide transparency from the perspectives of lighting and viewing angle with natural light, but also effectively convert sunlight into electrical energy. These solar windows are generally made of transparent or translucent materials, for example, those with a solar cell, such as a perovskite solar cell, embedded inside. This design can achieve partial energy self-sufficiency on the premise that the window does not affect the appearance of the building.

[0004] However, although solar windows have many advantages, they face some challenges. Some solar windows may lack flexibility in design, and thus are restricted when applied to various building environments, making it impossible to fully utilize light energy. In addition, perovskite solar cells are easily affected by environmental factors during actual application, resulting in oxidation of the perovskite solar cells and limiting the usable period of the solar windows.

[0005] Therefore, improving stability when actually applying perovskite solar cells, enhancing the effectiveness of applying solar panels to buildings, and providing diverse design options to promote the development of green buildings are issues that those involved should address as soon as possible. [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] The building shielding device further provided by the present invention includes an outer frame body comprising two side frames, an upper frame connected between the upper ends of the two side frames, and a lower frame connected between the lower ends of the two side frames, wherein the outer frame body has a perovskite photovoltaic module fitting groove formed on its interior and a second wire drilling portion, and two second retraction holes connected between the perovskite photovoltaic module fitting groove and the second wire drilling portion; and the perovskite photovoltaic module described above, wherein the periphery is fitted to the perovskite photovoltaic module fitting groove so as to be fixed by a filling material, and the positive electrode wire and the negative electrode wire of the perovskite photovoltaic module are drilled through the two second retraction holes into the second wire drilling portion. [Effects of the Invention]

[0009] The effect of the present invention is that, in the perovskite photovoltaic module, the first protective panel, the second protective panel, and the sealing body configuration are designed to surround the solar panel frame, thereby forming a sealed chamber, which effectively reduces the risk of oxidation of the perovskite cell. Therefore, when applied, it not only enhances stability but also extends the usable life of the product, giving it good potential for market application.

[0010] Furthermore, the building shielding device includes push doors, push windows, and fixed windows, or takes the form of glass guardrails or daylighting covers. In all cases, the outer frame is used to install the perovskite photovoltaic modules in combination with the building shielding device. This not only significantly enhances the effectiveness of applying solar panels to buildings, but also allows for the effective integration of renewable energy into daily life, providing buildings with a higher capacity for energy self-sufficiency. Moreover, the option to design these devices in a diverse manner allows architects and designers to create buildings with flexibility to meet different aesthetic and functional needs.

[0012] To further clarify the present invention, a detailed description will be given below with reference to the drawings, with reference to preferred embodiments. As shown in Figures 1 and 8, a perovskite photovoltaic module 100 according to a preferred first embodiment of the present invention, the perovskite photovoltaic module 100 includes a solar panel frame 10, four solar panels 20, a first protective panel 30, a second protective panel 40, and a sealing body configuration 50.

[0013] As shown in FIGS. 2, 3 and 5, the solar panel side frame 10 is a rectangular structure extruded from aluminum, and has four openings 11 and two first retreat holes 12 arranged in a 2×2 matrix. Each of the openings 11 is a rectangular hole chamber, and the two first retreat holes 12 are formed on one side of the solar panel side frame 10. As shown in FIGS. 5, 6 and 8, solar panel fitting grooves 14 are respectively formed around each of the openings 11 in the solar panel side frame 10. A first wire penetration part 13 is formed inside the solar panel side frame 10. The first wire penetration part 13 communicates with the two first retreat holes 12, and each of the solar panel fitting grooves 14 located around each of the openings 11 communicates with the two first retreat holes 12 through the first wire penetration part 13, so that each of the openings 11 and each of the solar panel fitting grooves 14 communicate with the two first retreat holes 12 respectively.

[0014] Each of the solar panels 20 is a rectangular plate body, and each of the solar panels 20 shields each of the openings 11 by fitting the portions located around the periphery with each of the solar panel fitting grooves 14 by means of an insulator 60. Specifically, the insulator 60 includes a plurality of gaskets 61. The plurality of gaskets 61 are arranged at intervals and abut against the inner wall of each of the solar panel fitting grooves 14 and the portions located around the periphery of the solar panel 20, so as to enhance the fixing effect of fitting the periphery of each of the solar panels 20 into each of the solar panel fitting grooves 14, and avoid the risk of short circuit caused by the direct contact between the solar panel 20 and the solar panel side frame 10. In other preferred embodiments, the solar panel side frame 10 is not limited to a frame structure extruded from aluminum, and the insulator 60 may also be changed from a plurality of gaskets 61 to one washer or a plurality of adhesive strips.

[0015] As shown in Figures 2, 3, and 8A, each of the solar panels 20 is a perovskite solar panel. Each solar panel 20 is constructed by press-fitting a perovskite photocell 201 between an upper package 202 and a lower package 203. The multiple solar panels 20 are connected in series by wires passing through the first wire drilling section 13. The multiple solar panels 20 are electrically connected in series and have a positive electrode wire 21 and a negative electrode wire 22, with the positive electrode wire 21 and the negative electrode wire 22 passing through the two first retractable holes 12, respectively. In this preferred embodiment, each of the perovskite photocells 201 is a double-sided cell, which increases the efficiency of absorbing light energy. In other preferred embodiments, the design of each solar panel 20 is not limited to a double-sided cell, and other types of perovskite photocell configurations may be adopted. Furthermore, the configuration is not limited to electrically connecting each of the aforementioned solar panels 20 to each other.

[0016] As shown in Figures 1, 2, and 8, the first protective panel 30 and the second protective panel 40 are both made of glass. More specifically, the first protective panel 30 and the second protective panel 40 are glass plates with an area slightly larger than the solar panel frame 10, and are attached to both sides of the solar panel frame 10, facing each other. The positive electrode conductor 21 and the negative electrode conductor 22 pass through the space between the first protective panel 30 and the second protective panel 40. The first protective panel 30 and the second protective panel 40 are each rectangular glass plates, and aluminum strips 65 are installed on each of the four sides of the first protective panel 30 and the second protective panel 40. The four aluminum strips 65 are long, hollow strips that surround the four sides of the solar panel frame 10. The aluminum strips 65 have through holes for the positive electrode conductor 21 and the negative electrode conductor 22 to pass through. Each of the plurality of aluminum strips 65 is filled with a desiccant 651, and an adhesive material is filled between the periphery of the first protective panel 30 and the second protective panel 40, making contact with the outer circumference of the plurality of aluminum strips 65, and solidifying the adhesive material to form the sealing body structure 50. The sealing body structure 50 surrounds the solar panel frame 10 while connecting with the periphery of the first protective panel 30 and the second protective panel 40, and makes contact with the outer circumference of the plurality of aluminum strips 65. The sealing body structure 50 also covers the portions of the positive electrode conductor 21 and the negative electrode conductor 22 that pass between the first protective panel 30 and the second protective panel 40. A sealed chamber 51 is formed between the first protective panel 30, the second protective panel 40 and the sealing body structure 50. The sealed chamber 51 isolates each of the solar panels 20 located inside from the outside, thereby preventing the perovskite photocells 201 in each of the solar panels 20 from oxidizing. The desiccant 651 is for further absorbing moisture inside the sealed chamber 51, and this design helps to further mitigate the problem of the perovskite photocells 201 in each of the solar panels 20 being susceptible to oxidation. This extends the stability and service life of each of the solar panels 20.In other preferred embodiments, the materials of the first protection panel 30 and the second protection panel 40 are not limited to glass, and may be other plate bodies through which light can pass. Around the solar panel side frame 10, without installing the plurality of aluminum strips 65, the sealing body structure 50 installed and connected around the solar panel side frame 10 to surround the peripheries of the first protection panel 30 and the second protection panel 40 may be directly installed.

[0017] In the solar panel side frame 10 of the perovskite solar power generation module 100, by providing the first wire drilling part 13 for communicating the plurality of openings 11 and the two first retreat holes 12 between them, it becomes easier to install and connect the wires for connecting the plurality of solar panels 20 in series. In addition, the first protection panel 30, the second protection panel 40 in the perovskite solar power generation module 100, and the periphery surrounded by the solar panel side frame 10 in the sealing body structure 50 form the sealing chamber 51. This design can effectively reduce the risk that the perovskite solar cells 201 in each solar panel 20 are oxidized, not only enhance the stability of applying the perovskite solar power generation module 100, but also extend the service life of the perovskite solar power generation module 100 and have good potential for market application.

Alternatively, the solar panel side frame 10 may have a plurality of openings 11, and one solar panel 20 may be installed in each of the plurality of openings 11.
