  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

  Please refer to FIG. As shown in FIG. 1, the photoelectric conversion device 10 according to an embodiment of the present invention converts light energy of a light source LS (for example, sunlight) into electric energy. The photoelectric conversion device 10 includes a tempered glass layer 12, a lens module 14, a substrate 16, and a heat dissipation unit 18. The tempered glass layer 12 is used to increase the surface hardness of the photoelectric conversion device 10 and protect the lens module 14. The lens module 14 has a plurality of lens units 142 provided on the top of the tempered glass layer 12. Between the lens unit 142 and the tempered glass layer 12, there is a gap Gp formed by a plurality of convex columns 144 and filled with a highly transparent colloid Gub. Here, since each of the convex columns 144 has the same height, when the gap Gp is filled with the high transparency colloid Rub, the thickness of the high transparency colloid Rub becomes the same as the height of the convex column 144, and the lens module 14 and the tempered glass The layer 12 is in close contact. Further, since the high transparency colloid Rub has a high coefficient of transparency, the loss of light energy of the light source LS can be minimized when it is transmitted through the high transparency colloid Rub. Since the high transparency colloid Rub has a low coefficient of thermal expansion, thermal expansion that occurs when light energy is transmitted can be reduced. The thickness of the highly transparent colloid Rub is preferably less than 1 mm. The substrate 16 has a plurality of receiving units 162 provided so as to correspond to the lens units 142, respectively. The receiving unit 162 converts the light energy received from the corresponding lens unit 142 into electric energy. The receiving unit 162 of the substrate 16 is installed at a focal position of the lens unit 142 or a position adjacent to the focal position of the lens unit 142 so that an optimum photoelectric conversion efficiency can be obtained. Is preferably focused on the receiving unit 162, respectively. The heat dissipating unit 18 is provided at the bottom of the substrate 16 and is used for releasing heat energy generated when converting the light energy from the lens unit 142.

  Please refer to FIG. As shown in FIG. 2, the lens module 14 of the photoelectric conversion device according to the embodiment of the present invention includes a plurality of lens units 142. The lens unit 142 has a plurality of convex columns 144 provided at a predetermined interval. These lens units 142 have a condensing characteristic and can concentrate (also referred to as focusing) a light source incident from the top in a predetermined region at the bottom. For example, the optimum light energy can be input to the lens unit 142 by effectively concentrating the light energy on the receiving unit 162 in order to concentrate the light source on the corresponding receiving unit 162.

  Please refer to FIG. As shown in FIG. 3, the tempered glass layer 12 used for protecting the lens unit 142 is disposed on the top of the convex column 144. Accordingly, it is possible to prevent the lens unit 142 from being damaged due to insufficient hardness and adversely affecting the photoelectric conversion efficiency. That is, it is possible to prevent the lens unit 142 left in the external environment from being exposed to direct sunlight or wind and rain to damage the surface and lowering the photoelectric conversion efficiency. Further, a gap Gp is provided between the tempered glass layer 12 and the lens unit 142 via a convex column 144. Since the high transparency colloid Rub injected into the gap Gp has a high transparency coefficient and a low thermal expansion coefficient, it prevents a diffraction phenomenon from occurring when light is transmitted from the tempered glass layer 12 to the lens unit 142. In addition, the tempered glass layer 12 and the lens unit 142 can be brought into close contact with each other. The thickness of the highly transparent colloid of this embodiment is less than 1 mm.

  Please refer to FIG. As shown in FIG. 4, the photoelectric conversion device 10 of FIG. 1 includes a plurality of modularized photoelectric conversion devices 10 'that are convenient for mounting. When a part of the photoelectric conversion device 10 ′ is damaged, it is not always necessary to replace the entire photoelectric conversion device 10, and only the damaged photoelectric conversion device 10 ′ can be replaced alone. Furthermore, the receiving unit is arranged so that the thermal energy generated when the receiving unit 162 of the photoelectric conversion device 10 ′ performs photoelectric conversion does not adversely affect the conversion efficiency and the service life of the components in the photoelectric conversion device. The receiving unit 162 dissipates heat by the heat dissipating unit 18 ′ provided at the bottom of the 162 substrate (shown in FIG. 5). The heat dissipating unit 18 ′ of the present embodiment is composed of a plurality of columnar heat dissipators that are columnar, rectangular columnar, or other columnar.

  Unlike the prior art, the photoelectric conversion device of the present invention has a high degree of modularity that can replace only a damaged lens when a part of the lens is damaged. Furthermore, since the lens is in close contact with the tempered glass layer through the convex column and the colloid, durability can be increased. Further, according to the present invention, the heat energy generated when performing photoelectric conversion can be effectively released by the heat dissipation unit provided at the bottom of the substrate having the receiving unit, so that the service life of the photoelectric conversion device can be extended. it can.

Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
