For ease of understanding, arrow a in fig. 2 shows the flow direction of the cooling water.
In some embodiments, as shown in fig. 1, heat exchange fins 5 are provided on the backlight surface 3 of the sub-battery unit 2.
The heat exchange fins 5 are used for increasing the heat exchange area of the sub-battery units 2 and the cooling water, and further improving the heat exchange efficiency and the heat exchange speed between the sub-battery units 2 and the cooling water.
Specifically, the extending direction of the heat exchanging fins 5 is perpendicular to the backlight surface 3 of the sub-battery unit 2.
In some embodiments, as shown in fig. 1, the heat exchange fins 5 are plural and uniformly distributed on the backlight surface 3 of the sub-battery unit 2.
The heat dissipation of the sub-battery units 2 is achieved through the plurality of heat exchange fins 5, so that the heat exchange area of the sub-battery units 2 and cooling water is further increased, and the heat dissipation efficiency of the sub-battery units 2 is improved.
Specifically, there is a suitable spacing between any adjacent two heat exchange fins 5.
In some embodiments, as shown in fig. 1, the upper end of the housing 1 is provided with an opening, and the PVT assembly further comprises a glass cover plate 6, the glass cover plate 6 being connected to the housing 1 and closing the opening.
The arrangement of the glass cover plate 6 slows down the heat dissipation of the sub-battery units 2 to the outside air, has the heat preservation effect, improves the heat absorption rate of the cooling water on the sub-battery units 2, and further improves the energy utilization rate.
Specifically, the glass cover plate 6 and the housing 1 may be detachably connected, and specifically, may be bolted, clamped, or the like. Thereby facilitating the removal of the glass cover plate 6 for routine maintenance and/or replacement of the sub-battery units 2 within the housing 1.
For ease of understanding, arrow B in fig. 1 shows the up and down direction of the PVT assembly.
In some embodiments, the wall of the housing 1 for constituting the fluid chamber comprises an insulating layer.
Therefore, the heat dissipation in the shell 1 is further slowed down, and the absorption rate of cooling water to the heat in the shell 1 is further improved, so that the energy utilization rate is improved.
In particular, the walls of the housing 1 may be made of a thermally insulating material, i.e. the walls of the housing 1 are thermally insulating layers. Alternatively, the inner and/or outer surfaces of the walls of the housing 1 are coated or clad with a heat insulating material to form a heat insulating layer.
In some embodiments, as shown in fig. 1, the subcell unit 2 includes a first subcell 21 and a second subcell 22, the first subcell 21 having a first light surface 211 and the second subcell 22 having a second light surface 221, the first light surface 211 and the second light surface 221 being at an angle therebetween, the first subcell 21 and the second subcell 22 having different band gaps.
When the first sub-cell 21 and the second sub-cell 22 are irradiated by sunlight, the first illumination surface 211 can reflect light in an unabsorbed wavelength response range onto the second illumination surface 221 while absorbing sunlight, so that the absorption amount of the light in the corresponding wavelength response range by the second illumination surface 221 is increased; the second illumination surface 221 may reflect light of an unabsorbed wavelength response range onto the first illumination surface 211 while absorbing sunlight, increasing an absorption amount of the first illumination surface 211 for light of a corresponding wavelength response range, thereby improving an absorption rate of solar energy.
In addition, the first sub-battery 21 and the second sub-battery 22 are arranged at an angle, so that the first illumination surface 211 and the second illumination surface 221 are not mutually blocked, the effect that solar rays can be completely directly irradiated on the first illumination surface 211 and the second illumination surface 221 is ensured, the problem that the solar rays are blocked due to the fact that a plurality of sub-batteries are vertically stacked in the related laminated battery is solved, and current mismatch of the sub-batteries at the lower layer is caused, and therefore stable performance of the sub-battery unit 2 is ensured.
In some embodiments, as shown in fig. 1, the first side of the first sub-cell 21 and the first side of the second sub-cell 22 are hermetically connected to form a first angle structure, the first angle structure forms a concave angle with respect to the irradiation direction of sunlight, and the angle between the first sub-cell 21 and the second sub-cell 22 is equal to 45 degrees.
The first side of the first sub-battery 21 is connected with the first side of the second sub-battery 22 in a sealing way, so that the cooling water is prevented from overflowing upwards from the connecting part of the first sub-battery 21 and the second sub-battery 22, the normal absorption of solar energy by the sub-battery unit 2 due to the cooling water is avoided, and the working effectiveness of the sub-battery unit 2 is ensured.
The first included angle structure makes the arrangement of the first illumination surface 211 and the second illumination surface 221 compact on the one hand, and reduces the occupied space; on the other hand, the interval between the first light surface 211 and the second light surface 221 is eliminated, and when the first light surface 211 and/or the second light surface 221 reflect sunlight, the sunlight is prevented from leaking from the interval position, so that the receiving amount of the reflected light of the sunlight by the first light surface 211 and/or the second light surface 221 is increased, and the absorptivity of the sunlight is improved as a whole.
The included angle between the first sub-cell 21 and the second sub-cell 22 is equal to 45 degrees, so that the first illumination surface 211 can absorb sunlight in the corresponding wave band in a large area and reflect sunlight in the wave band corresponding to the second illumination surface 221; the second illumination surface 221 can absorb sunlight in a corresponding wavelength band in a large area, and reflect sunlight in a wavelength band corresponding to the first illumination surface 211, thereby further improving the absorption rate and the utilization rate of the sunlight.
In some embodiments, a first reflection enhancing film is laid on the first illumination surface 211, the first reflection enhancing film corresponds to the second sub-cell 22 and is used for reflecting the wavelength band absorbed by the second sub-cell 22, and a second reflection enhancing film is laid on the second illumination surface 221, and the second reflection enhancing film corresponds to the first sub-cell 21 and is used for reflecting the wavelength band absorbed by the first sub-cell 21.
The first reflection enhancing film further improves the reflection effect of the first illumination surface 211 on sunlight, and meanwhile, the arrangement of the first reflection enhancing film realizes selective reflection of sunlight with different wave bands, so that the second illumination surface 221 is convenient for absorbing light energy with a required wave band.
In addition, the second reflection enhancing film further improves the reflection effect of the second illumination surface 221 on sunlight, and meanwhile, the arrangement of the second reflection enhancing film realizes selective reflection of sunlight with different wave bands, so that the first illumination surface 211 can absorb light energy with a required wave band conveniently.
The reflection enhancing film with different thickness responds to the sunlight with different wave bands/spectral regions, and the reflectivity of the sunlight in the wave band is improved, so that the reflection intensity of the sunlight in the wave band is increased, and therefore, the light with the wave band corresponding to the second sub-cell 22 can be reflected by adjusting the thickness of the first reflection enhancing film, and the reflectivity and the reflection intensity of the light with the wave band are improved; by adjusting the thickness of the second reflection enhancing film, it is possible to reflect light of a wavelength band corresponding to the first subcell 21 and to increase the reflectance and reflection intensity of light of the wavelength band.
In some embodiments, at least one of the first and second antireflective films is a reflective film doped with quantum dot fluorescent material.
The reflecting film with the quantum dot fluorescent material can realize the effect of down-converting ultraviolet light, thereby further improving the absorptivity and the utilization rate of sunlight.
Specifically, the quantum dot fluorescent material can absorb ultraviolet light, and simultaneously emits a light beam with a certain wavelength, and the wavelength of the light beam is in a wave band corresponding to the first illumination surface 211 or the second illumination surface 221, so that the quantum dot fluorescent material can realize the conversion of the wavelength of the ultraviolet light, and the conversion of the wavelength of the ultraviolet light into sunlight which is convenient for the first illumination surface 211 or the second illumination surface 221 to absorb, thereby realizing the secondary absorption of the first illumination surface 211 or the second illumination surface 221 to the sunlight, solving the problem that the photovoltaic cell has poor response or cannot respond to the ultraviolet light in the related art, and improving the absorption rate and the utilization rate of the sunlight.
Preferably, the first reflection enhancing film and the second reflection enhancing film are both reflecting films doped with quantum dot fluorescent materials.
In some embodiments, as shown in fig. 1, a plurality of sub-battery units 2 are sequentially arranged along a first direction, and a first sub-battery 21 and a second sub-battery 22 in each sub-battery unit 2 are arranged along the first direction, and a second side of the first sub-battery 21 and a second side of the second sub-battery 22 in any two adjacent sub-battery units 2 are connected in a sealing manner to form a second included angle structure, and the second included angle structure forms a convex angle relative to the irradiation direction of sunlight.
The arrangement of two adjacent sub-battery units 2 becomes compact due to the second included angle structure, and the occupied space of the sub-battery units 2 in the photovoltaic cell is greatly reduced.
A sealed chamber 7 is formed between each of the plurality of sub-battery cells 2 and the glass cover plate 6, and the sealed chamber 7 is filled with an inert gas.
The inert gas fills the area between the glass cover plate 6 and the sub-battery cells 2, preventing oxygen from entering the area, thereby slowing down the degradation of the sub-battery cells 2 and their film layers.
As shown in fig. 1, a plurality of support plates 8 corresponding to the connection parts of the first sub-battery 21 and the second sub-battery 22 one by one are arranged in the shell 1, the first ends of the support plates 8 are connected with the connection parts of the corresponding first sub-battery 21 and the second sub-battery 22, and the second ends of the support plates 8 are connected with the bottom surface of the shell 1. The support plate 8 is used for supporting the gravity of the first sub-battery 21 and the second sub-battery 22, and the length direction of the support plate 8 is consistent with the length direction of the first sub-battery 21 or the second sub-battery 22.
The first direction is orthogonal to the flow direction of the cooling water in the housing 1.
For ease of understanding, arrow C in fig. 1 shows a first direction of the PVT assembly.
In addition, according to the PVT assembly of the embodiment of the present invention, the plurality of sub-battery units 2 in the housing 1 are arranged in a folded and undulating manner, so that compared with a conventional stacked battery, the contact area between the backlight surface 3 of the single sub-battery unit 2 and the cooling water is greatly increased, that is, the backlight surface 3 can be basically and completely contacted with the cooling water, thereby further improving the heat dissipation efficiency of the sub-battery unit 2, avoiding the influence of heat accumulation on the stability of the device, and simultaneously improving the heating efficiency of the cooling water.
