Solar cell module provided in this embodiment, including component body, component body are erected instead of in glass curtain wall
The ordinary glass being directly arranged substantially is communicated with traditional glass curtain wall as metope, installation form.
The day side of component body convexes to form several fins, and fin extends along horizontally or diagonally direction, and each fin is along vertical
To arrangement, to change the incidence angle size for the light that component body is an actually-received.
There are many structure types for fin, can be such as the fin that top surface is scabbled, section can be trapezoidal, or no
Regular quadrilateral.When fin section is trapezoidal, the part plane parallel with vertical plane will not play the role of anti-reflection anti-reflection,
The inclined surface that top is only located in trapezium structure can play the role of reducing incidence angle；When fin section is irregular quadrilateral
When, preferably there are two plane and a plane obliquely obliquely, the plane energy of two be located above obliquely for fin
Play the role of anti-reflection anti-reflection, the degree difference only each reduced in face of incidence angle.Fin can be wedge angle fin, section
For triangle, in the present embodiment, the fin used is wedge angle fin.
It is illustrated below for wedge angle fin.In the present embodiment, the facade of the battery component after installation is towards south.Such as Fig. 3
With shown in Fig. 4, wedge angle fin 4 is horizontally extending, and each wedge angle fin 4 is along component body longitudinal arrangement.
It is subject to the crest line 43 of wedge angle fin 4, the face of 43 top of crest line is upper side 41, and the face of 43 lower section of crest line is downside

The mainly irradiation by the main sunny slope reflected light for the fin being disposed below of face 42, therefore downside 42 is formed as secondary and faces south
Face.
Specific fin cross sectional shape can also be as shown in Figure 2, as long as guaranteeing at least one face obliquely with shape
At main sunny slope, a face obliquely to form time sunny slope.
As shown in Figure 3, set wedge angle fin 4 upper side 41 and horizontal plane angle as α, fin downside 42 with
The angle of horizontal plane is β.As shown in Figure 1, the incidence angle θ of light is equal to solar elevation at that time when being not provided with fin, setting
When such as fin in Fig. 2, light incident direction is constant, but actual incidence angle becomes between incident light and fin upper side normal
Angle, it is clear that actual incidence angle substantially reduces relative to former incidence angle, thus can be greatly reduced because incidence angle it is larger caused by
Transmitted ray decaying, and then improve enter solar battery light intensity, improve conversion of solar energy.As shown in Figure 2, on fin
Side also changes the reflection path of light, and when being not provided with fin, the direction of former reflected light obliquely, after fin is arranged, is reflected
The direction of light becomes obliquely, in this way it is possible to prevente effectively from noon sun is reflected into ground by skyscraper, and then avoids dizzy
Light pollution problem.In addition, enabling the light after the reflection of the fin of lower section to be radiated at by the way that each fin to be arranged in the vertical direction and facing

Level angle, therefore for the glass curtain wall of east orientation, sunlight is usually injected from its upper right side, i.e. south orientation sunlight, convex at this time
The main light-receiving surface of rib should tilt obliquely towards upper right side, i.e. fin.Similarly, convex for west to the glass curtain wall of facade
Rib tilts arrangement obliquely.
Solar cell module provided by the utility model, by the way that several fins are arranged in the day side of component body, and
By fin in the horizontal direction or inclined direction extend, each fin is arranged in the vertical direction, the photovoltaic curtain wall being vertically arranged can be changed
The incidence angle size of light-receiving surface.When the meridian hour solar elevation is larger, light with biggish incidence angle directive component body,
And having certain angle between the main light-receiving surface and vertical plane of fin, the angle is that is, have fin and incidence angle when without fin
Difference, be equivalent to the incidence angle size for reducing the light being actually radiated in component body, avoid light in incidence angle
The decaying of transmitted ray caused by when larger, to avoid the problem that solar cell module transformation efficiency is low in this case；Fin
The reflection path of light can also be changed, it is possible to prevente effectively from noon sun is reflected into ground by skyscraper, and then avoided dizzy
Light pollution problem；In addition, enabling the light after the reflection of a certain fin convex as closing on by the way that each fin to be arranged in the vertical direction
The incident light of rib, makes full use of reflection light, reduces the loss of reflected light, and then increase the light intensity for being incident upon component body, with
