In addition, it should be noted that the bottom plate 21 is further coated with an electrically insulating heat-radiating paint (not shown) to electrically insulate the frame 20 and prevent electric leakage, and the electrically insulating heat-radiating paint can also increase the corrosion resistance and scratch resistance of the bottom plate 21 and improve the heat dissipation capability of the solar chip 23, and in addition, a protection member 27 is correspondingly disposed at four corners of the frame, and the protection member 27 can be made of metal material or polymer material such as aluminum, iron, polyphenylene oxide (PPO), polybutylene terephthalate (PBT).

In this embodiment, the substrate 22 is an aluminum substrate, a copper substrate, a ceramic substrate, a metal substrate, or a copper-aluminum bump aluminum substrate (Super pilar MCPCB)220, wherein a bump 2201 is further formed on one side of the copper-aluminum bump aluminum substrate 220 (see fig. 3), a back electrode 230 is formed at the bottom of the solar chip 23 and correspondingly attached to the bump 2201, and the design of the bump 2201 formed on the copper-aluminum bump aluminum substrate 220 is utilized to enable heat of the solar chip 23 to rapidly leave away, so as to increase the heat dissipation efficiency, and in addition, an insulating layer 231 is further formed at the bottom of the solar chip 23 to overcome the short circuit problem.

The bottom plate 21 is made of aluminum for use as a heat sink (for dissipating heat from the substrate 22), but other metal materials with high thermal conductivity may be used, as described above, and the substrate 22 may be fixed on the bottom plate 21 by screws or rivets or other equivalent means.

The lens set 25 is composed of a glass plate 250 and a colloid 251, and the lens set 25 is correspondingly assembled at one side of the frame 20, more specifically, the lens set 25 is manufactured by pressing the glass plate 250 and the colloid 251 through a mold (not shown) to form a structure of a fresnel lens, it should be noted that, the number of the toothed rings of the lens set 25 is 8 to 30 rings, the larger the number of the toothed rings is, the less the material is used, the thickness of the lens set 25 is relatively thin, and the larger the number of the toothed rings affects the optical scattering effect, the lens set 25 is correspondingly assembled at the open side 200 of the frame 20 to form a closed high power concentrating power generating structure and device 2, so the sunlight firstly passes through the lens set 25 and then is transmitted into the solar energy accommodating space 204 to be received by the solar energy chip 23, so that light energy can be converted into electric energy.

The colloid 251 is selected from any one of optical silica gel (silicone) or Ethylene Vinyl Acetate (EVA) or polyvinyl butyral (PVB), and the sol 251 is coated on the glass plate 250 and then subjected to compression molding, baking, drying, demolding and other steps by a mold to form an sog (silicone on glass) lens set 25 or an eog (EVA on glass) lens set 25 or a pog (PVB on glass) lens set 25 with high surface scratch resistance.

Referring to fig. 4, in practical implementation, the present invention shows that six high-concentration solar power generation structures and devices 2 are used in parallel (the number of the high-concentration solar power generation structures and devices can be adjusted according to the user's needs), and the lens assembly 25(SOG, EOG, or POG) made by combining the glass plate 250 and the colloid 251 not only can increase the light receiving area and reduce the optical invalid area, but also can greatly improve the photoelectric conversion efficiency.

Finally, please refer to fig. 5, which is an exploded perspective view of a second embodiment of the high power concentrating solar power generation structure and device of the present invention, wherein the corresponding relationship between the components and parts of the high power concentrating solar power generation structure and device is the same as the aforementioned high power concentrating solar power generation structure and device, and therefore will not be described herein, but the most important difference between the high power concentrating solar power generation structure and device and the aforementioned is that the frame 20 further has a first inner sidewall 202 and a second inner sidewall 203, the first inner sidewall 202 is opposite to the second inner sidewall 203, at least one vent 205 is disposed on the first and second

inner sidewalls

202, 203, the vent 205 is disposed on the first inner sidewall 203 for illustration, and in practice, the disposition position, the disposition number, and the size of the vent 205 can be adjusted by users, the vent hole 205 is communicated with the accommodating space 204 of the frame 20, at least one film 26 is correspondingly disposed on the vent hole 205, the shape of the film 26 is illustrated as a circle, but not limited thereto, and in practical implementation, the film 26 may also be in a rectangular or other geometric structural form, as will be described in the foregoing.

Because the frame 20 is a closed structure, the internal pressure of the frame 20 will increase in a high-sunlight environment and decrease in a low-sunlight or no-sunlight environment, and therefore the high-concentration solar power generation structure and the device 2 are easily damaged if no proper pressure discharge mechanism is provided under periodic circulation, and therefore, the air permeable film with the air permeable effect of the film 26 is utilized to balance the internal and external pressures of the frame 20 and prevent dust and liquid from entering the accommodating space 204 of the frame 20, thereby achieving the dustproof and waterproof effects.
