Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment one
FIG. 1 to FIG. 6 is please referred to, solar battery provided by the embodiment of the utility model includes: solar battery chip 1,
At least one surface of the solar battery chip 1 is formed with color control layer 2.Color control layer 2 is for adjusting difference
The light color that light reflection angle is reflected.Color control layer 2 can be anti-reflection film.Wherein, solar battery chip 1 can be with
For flexible solar battery chip or it is difficult to the rigid solar battery chip bent.Flexible solar battery chip is usually thin
Film solar cell chip, is of course not solely limited to this；Rigid solar battery chip is usually Monocrystalline silicon cell piece, certainly not only
It is limited to this.
In use, a portion light passes through as color control layer 2 when ambient irradiates solar battery
Anti-reflection film directive solar battery chip 1, this some light is absorbed by solar battery chip 1, and solar battery chip 1 utilizes
Absorbed light generates electricity, and another part light reflects solar battery by the anti-reflection film as color control layer 2；Such as
Fruit solar battery chip 1 reflects some light, so that the light reflected by solar battery chip 1, which passes through, is used as color
The anti-reflection film of control layer 2, then this some light will also project solar battery.And due to as the anti-reflection of color control layer 2
Film is adjustable the light color that different light angles of reflection are reflected, so that the anti-reflection film as color control layer 2 can control difference
The light color that light reflection angle is reflected, to guarantee reflected light color diversification.It is understood that reflection

2 anti-reflection film of layer and the mutual alignment relation of solar battery chip 1, can have the following two kinds implementation.
The first implementation: as shown in Figure 1-Figure 3, along the thickness direction of solar battery chip 1, insulating protective layer
3 between the surface of solar battery chip 1 and the anti-reflection film as color control layer 2.At this time since insulating protective layer 3 will
Solar battery chip 1 and anti-reflection film as color control layer 2 separate, so that solar battery chip 1 and color control layer 2
Anti-reflection film mutually insulated, therefore, whether the above-mentioned anti-reflection film as color control layer 2 conductive, will not influence solar battery
The photoelectric current of chip 1 exports.Moreover, it is contemplated that there is extraction electrode to the surface of solar battery chip 1, it is easy so that solar energy
Therefore the surface irregularity of battery chip 1 first can form insulating protective layer 3 on the surface of solar battery chip 1, so
The anti-reflection film as color control layer 2 is formed on the surface of insulating protective layer 3 again afterwards, so that insulating protective layer 3 is to solar-electricity
The surface in pond carries out planarization process, to guarantee to be formed by the increasing as color control layer 2 on the surface of insulating protective layer 3
Permeable membrane has stable light transmission and reflection function, so that reflection of the directive as the light of the anti-reflection film of color control layer 2
With refraction controllableization.
In this implementation, above-mentioned insulating protective layer 3 can cover simultaneously lead forming region T1 and coloring forms area
Domain T2 can also be covered only in coloring forming region T2, be selected with specific reference to actual conditions.
Illustratively, as shown in Fig. 2, when the above-mentioned insulating film as color control layer 2 had both covered lead forming region T1
Again when covering coloring forming region T2, above-mentioned insulating protective layer 3, which covers lead forming region T1 simultaneously and covers to colour again, forms area
Domain T2 provides flat formation surface to the anti-reflection film as color control layer 2 to guarantee.In addition, working as insulating protective layer 3 simultaneously
Covering coloring forming region T2 and lead forming region T1, so that 3 one side of insulating protective layer is used as planarization layer, it is another
Direction is also used to protect lead electrode.

The anti-reflection film stacking of preparative layer 2 is located at coloring forming region T2, may make lead forming region T1 exposed.At this point, can complete
After all film layers production of solar battery sheet, contact conductor 110 is finally located at lead forming region T1 again, this makes the sun
The processing procedure of energy battery is more reasonable.
Specifically, when insulating protective layer 3 and as color control layer 2 anti-reflection film be laminated be located at coloring forming region
When T2, the production of solar battery can be divided into film layer formation process and lead formation process, so that complete in film layer formation process
At solar battery all film layers make, and lead formation process can be by the electricity of contact conductor 110 and solar battery
Pole layer connection.If lead forming region T1 does not have exposed, need in film layer manufacturing process, lead forming region T1 also
When being in naked state, contact conductor 110 is placed in lead forming region T1 in advance, then proceeds by the production of other film layers,
This makes the manufacturing process of solar battery excessively cumbersome, it is difficult to which smoothness carries out.
