Background technology
At present, photovoltaic welding belt is crucial auxiliary material solar cell being connected bunchiness, and solar cell forms a complete electric path after being connected by welding, luminous energy is converted into electric energy by solar cell, the electric current produced forms transmission circuit by welding, provides path basis for utilizing solar energy.Existing common welding is comparatively smooth through welding rear surface, and enter the light of assembly to smooth welding surface, gone out cannot be utilized by mirror-reflection, the utilance of incident light is very low; In order to increase operation rate, some special special-shaped weldings of current existence, Surface Machining becomes certain reflective groove structure, the angle Φ 1 of surface reflection groove is in 111 ° ~ 137 °, and the reflecting coating on surface is the high reflectance high-melting-point noble metals such as Ag, and the coating on surface is generally 1 ~ 5 μm, when light incides the reflection of groove structure through certain angle groove structure, secondary reflection again through glass, Air Interface arrives cell piece surface, is again utilized, thus improves the utilance of incident light.
The Chinese patent being 201320775180.1 at application number discloses a kind of micro-optically focused synergy photovoltaic welding belt, it comprises base band and is arranged on the reflected coat layer on base band sensitive surface, the shady face of base band is flat surface, the sensitive surface of base band is provided with the reverse V-shaped sawtooth of multiple projection, and the sensitive surface of base band be provided with between adjacent reverse V-shaped sawtooth recessed to shady face side and be used for storing the accumulator tank of remelting back reflection coating material, the angle β of reverse V-shaped sawtooth is 106 ° ~ 137 °.The utility model has taken into full account the change of welding back reflection coating surface topography after reflow, increases effective light-collecting area of welding, thus improves photovoltaic module power.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of micro-condensation photovoltaic welding improving incident light utilance, improve photovoltaic module power.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of micro-optically focused synergy photovoltaic welding belt, comprise base band and be arranged on the reflected coat layer on described base band sensitive surface, the shady face of base band is plane, it is characterized in that, described base band sensitive surface is provided with the projection of multiple protrusion, the surface of described projection is arc, has spacing between described projection, and the shortest spacing between described projection is less than or equal to the spacing between protruding bottom.
Further, the shortest spacing between described projection is less than the spacing between protruding bottom.
Further, described projection is hemisphere.
Further, the height of described projection is 80 ~ 140 μm, and the width of described projection is 80 ~ 160 μm, and the shortest spacing between described projection is 50 ~ 70 μm, and the spacing between described protruding bottom is 50 ~ 90 μm.
The beneficial effect that the utility model has:
Base band sensitive surface is provided with the projection of multiple protrusion, protruding surface is arc, phase specific surface is plane or is zigzag inclined-plane, arc has wider reflected range, incident light can be reflected toward all angles, be reflected to again on the sensitive surface of base band through glass, improve the utilance of incident light.
And by arranging special structure and size, in the bottom of projection, the sunlight entering to shine when certain angle through first reflection back reflection on projection arc sphere on lower side, can reflex to again on another adjacent projection arc sphere on lower side, finally reflex to again on the sensitive surface of welding, can not reflect away, further increase the utilance of incident light, and then improve the power of photovoltaic module.

Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.
As depicted in figs. 1 and 2, a kind of micro-optically focused synergy photovoltaic welding belt, the reflected coat layer comprising base band 1 and be arranged on described base band 1 sensitive surface, the shady face of base band 1 is plane, base band 1 sensitive surface is provided with the projection 2 of multiple protrusion, and the surface of protruding 2 is arc, phase specific surface is plane or is zigzag inclined-plane, arc has wider reflected range, incident light can be reflected toward all angles, improves the utilance of incident light further.Have spacing between the projection 2 of arc, and the shortest spacing between protruding 2 be less than or equal to bottom protruding 2 between spacing.
The height of protruding 2 is 80 ~ 140 μm, and the width of protruding 2 is 80 ~ 160 μm, and the shortest spacing between protruding 2 is 50 ~ 70 μm, and the spacing between bottom described protruding 2 is 50 ~ 90 μm.
Continue shown in composition graphs 2, Fig. 3 and Fig. 4, be respectively three kinds of embodiments of the present utility model, in Fig. 2 of embodiment 1, arc convex 2 volume is less than hemisphere; In Fig. 3 of embodiment 2, arc convex 2 volume equals hemispherical volume, and namely protruding 2 is hemispheric structure; In Fig. 2 and Fig. 3, the spacing between the shortest spacing between protruding 2 equals bottom protruding 2.
In Fig. 4 of embodiment 3, protruding 2 volumes are greater than hemisphere, therefore, spacing between shortest spacing between protruding 2 is less than bottom protruding 2, this is also a kind of preferred execution mode, because the part below hemisphere, the sunlight entering to shine when certain angle through first reflection back reflection on protruding 2 arc spheres on lower side, and through this arc spheric reflection back reflection on another adjacent projection 2 arc sphere on lower side, finally reflex to again on the sensitive surface of welding 1, can not reflect away, further increase the utilance of incident light.Certainly, in this case, the spacing between protruding 2 is then very important, if spacing is too little, then incident light can not well enter in the gap between protruding 2, and utilance can decline on the contrary.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
