Definitions

  • the present invention relates to a window assembly, and more particularly, to a window assembly comprising a solar cell capable of producing electricity by receiving light incident from the outside.
  • the solar cell is generally made of a transparent material so that some of the light incident from the outside is irradiated into the room.
  • a transparent solar cell has a higher manufacturing cost than a general solar cell, and thus has a problem in that a manufacturing cost of a window including a solar cell is high.
  • An object of the present invention is to provide a window assembly which is not reduced in the amount of light irradiated into the room and which is low in manufacturing cost.
  • the solar cell is disposed along the circumference of the light transmitting member, it is possible to minimize the amount of light lost in the process of transmitting light.
  • the solar cell included in the window assembly as described above is interposed between the light transmitting member and the frame. Therefore, since the solar cell is not disposed at a position that prevents light from being transmitted, it is not necessary to use a transparent solar cell unlike a conventional window or window. In other words, the manufacturing cost of the window assembly can be minimized since it is not necessary to use a relatively expensive transparent solar cell in manufacturing the window assembly of the present invention.
  • light is induced and transmitted to a solar cell disposed perpendicular to the edge of the light transmitting member by a light transmitting member having a refractive index higher than that of air, thereby increasing the amount of light transmitted to the solar cell, thereby increasing power generation efficiency per unit solar cell. It can be maximized.
  • FIG. 1 is a cross-sectional view of a window assembly according to a preferred embodiment of the present invention.
  • Figure 2 is a perspective view of a window assembly according to another embodiment of the present invention.
  • FIG. 3 is a cross-sectional view of the window assembly shown in FIG.
  • FIG. 4 is a view for explaining a process of light is guided to the solar cell by the light guide member of the window assembly shown in FIG.
  • FIG. 5 is a perspective view showing a window assembly according to another embodiment of the present invention.
  • a window assembly 100 includes a light transmitting member 110, a frame 120, and a solar cell 130.
  • the light transmitting member 110 is made of a first material.
  • the shape of the light transmitting member 110 may be a plate shape of a specific thickness.
  • One example of the first material may be glass. Glass is a material with high strength and high light transmittance. Such glass is an advantageous material for allowing external light to pass through.
  • the first substance is not limited to glass.
  • the frame 120 is formed along the circumference of the light transmitting member 110.
  • the frame 120 prevents the light transmitting member 110 from being damaged by an external impact.
  • An example of the material of the frame 120 may be reinforced plastic.
  • another example of the material of the frame 120 may be aluminum or steel.
  • the solar cell 130 is interposed between the light transmitting member 110 and the frame 120.
  • the solar cell 130 utilizes the photovoltaic effect of a semiconductor such as silicon, and converts light energy emitted from the sun into electrical energy.
  • An example of such a solar cell 130 may be a semiconductor solar cell 130.
  • the solar cell 130 may be a Si-based (poly-crystalline, crystalline, amorphous) and GaAs compound solar cell even in a semiconductor solar cell.
  • the solar cell 130 is not limited to being a semiconductor solar cell.
  • the solar cell 130 is disposed along the circumference of the light transmitting member 110, it is possible to minimize the loss of light in the process of transmitting light.
  • the solar cell 130 included in the window assembly 100 as described above is interposed between the light transmitting member 110 and the frame 120. Therefore, since the solar cell 130 is not disposed at a position that prevents light from being transmitted, it is not necessary to use a transparent solar cell unlike a conventional window or window. That is, in manufacturing the window assembly 100 of the present invention, it is not necessary to use a relatively expensive transparent solar cell, thereby minimizing the manufacturing cost of the window assembly 100.
  • Light reflects total reflection and refraction depending on the angle of incidence at the interface between two materials having different refractive indices, and light can be effectively induced into a material having high refractive index by this physical phenomenon. Since the light transmitting member 110 has a higher refractive index than air, a part of the transmitted light is propagated from the inside to the edge surface through total reflection and refraction, so that the light is efficiently transmitted to the solar cell attached to the edge surface. Power generation efficiency can be expected.

As shown in FIG. 4, the light guide member 140 having a different refractive index than the light transmitting member 110 may increase the function of inducing at least a part of light incident from the outside into the solar cell 130 more efficiently.
  • the light guide member 140 is preferably made of a transparent material. This is to minimize the loss of light in the process of transmitting the light guide member 140. More preferably, the transparency of the light guide member 140 may be 70% or more.
  • glass may be used as an example of the second material constituting the light guide member 140, a silicate-based glass containing SiO 2 as a main component, a boric acid-based glass containing B 2 O 3 as a main component, P 2 It may be one selected from a phosphate-based glass containing O 5 as a main component and a tellurite-based glass containing TeO 2 as a main component. It is preferable that the second material differ from the first material by at least 0.005 refractive index.
  • the process conditions for forming the second material on the light transmitting member 110 should have physical properties in a range that does not cause deformation of the first material.
  • the firing temperature of the second material is the strain point or softening point of the first material. It must be lower than the temperature.
  • the light guide member 140 is easy to add active ions to absorb the ultraviolet light to convert to a wavelength suitable for improving visible light or solar cell efficiency, it can be improved efficiency.
  • a transparent plastic material may be used, but the second material is not limited to plastic.
  • a screen printing method may be used as an example of a method of forming the light guide member 140 on the light transmitting member 110.
  • the mask is attached only to a portion of the light transmitting member 110 in which the light guide member 140 is not formed. That is, the mask is a thin film-shaped member formed so that the portion where the light guide member 140 is to be formed is opened.
  • the paste serving as the material of the light guide member 140 is applied to the opened portion of the mask.
  • the squeegee is moved in one direction to be in close contact with the mask surface to planarize the paste applied to the light transmitting member 110 and the mask.
  • the flattened paste is fired to complete manufacture of the light guide member 140.
  • the process can be performed at a temperature of approximately 500 to 600 with the first material being glass.
  • This method can not only make the thickness of the light guide member 140 uniform, but can also prevent bubbles from being generated between the light transmitting member 110 and the light guide member 140. Bubbles can impede the light from being directed to the solar cell, thereby reducing the efficiency of the solar cell. In addition, the bubbles do not make the appearance of the window assembly beautiful.
