Description
Technical field
The present invention relates to novel solar battery assembly, belong to the technical field of semiconductor device of encapsulation.
Background technology
At present, solar module mainly by some solar cell use interconnecting strip carry out series connection be shaped to group string, some battery pack strings are connected in series according to the arrangement of certain square formation, use busbar again, carry out encapsulating and the solar module formed, be subject to the welcome in market with its exclusive characteristic.In prior art, the function singleness of solar module and there is following defect: (1) this type of solar module, owing to being only made up of a series circuit, the interconnecting strip of sheet solar cell battery surface is comparatively large by electric current, and the power loss caused because of interconnecting strip resistance is higher; (2) if " hot spot phenomenon " that electric current is too low appears in one of them cell piece of whole solar module, this sector-meeting as a load consumption, thus has influence on the transformation efficiency of whole solar module.
Summary of the invention
The object of the invention is to the above-mentioned defect overcoming the existence of existing solar module, propose a kind of novel solar battery assembly, carry out cutting setting by substring group is parallel with one another with cell piece, achieve the function that power income improves.
The present invention adopts following technical scheme to realize: a kind of novel solar battery assembly, comprise the battery strings group of series connection mutually, battery strings group comprises substring group parallel with one another, and the cell piece that each substring group is cut by homalographic is in series by interconnecting strip.In substring, solar cell is by traditional solar cell excision forming, and this feature can ensure that solar module voltage exports on immovable basis, obtains more power income.
Further, battery strings group is at least provided with two groups.
Further, substring group is at least provided with two groups.
Further, the circuit of each substring group comprises at least one diode.
Further, interconnecting strip connects another string group same polarity and diode end.
Further, the cell piece of homalographic cutting is provided with white space.White space between cell piece increases, thus can increase the light source being transmitted into cell piece surface, have also been obtained the effect improving solar module power.
Further, cell piece put in order and size according to setting specification adjustment.
The invention has the beneficial effects as follows:
(1) novel solar battery assembly of the present invention, ensures that solar module voltage exports on immovable basis, obtains more power income;
(2) novel solar battery assembly of the present invention, use the arrangement mode of cutting cell piece, white space between cell piece increases, thus can increase the light source being transmitted into cell piece surface, have also been obtained the effect improving solar module power.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment one:
As shown in Figure 1, novel solar battery assembly of the present invention, traditional solar module comprises the solar cell that several (72pcs) connect mutually, and the cell piece 3 of solar energy, according to the arrangement of certain permutation, connects into battery strings group by interconnecting strip 2.String group uses busbar 1 to connect, and form large-area solar module, a diode in two battery strings terminal boxes is protected, as shown in Figure 2.
The present invention proposes novel solar module, and it comprises three battery strings groups of mutually connecting, and each string group comprises several substring groups parallel with one another, and each substring group is that the cell piece 3 cut by some homalographics uses interconnecting strip 2 to connect.
The present invention is the improvement to conventional solar cell assembly, and its prerequisite implemented ensures that each performance exports not do and change, and on the installation and maintenance of photovoltaic plant without impact, therefore is cut by cell piece 3.As shown in Figure 3, and be homalographic segmentation, then pass through and the mode of connecting, the electric current and voltage of the solar components that solar cell of the same area is formed exports unchanged, and the power of solar components or conversion ratio can obtain the raising of certain amplitude.
Solar cell sizes the most conventional in the current industry is 156 × 156mm, Fig. 3 is only cut this battery, but the size of solar cell is not limited only to this, can also be other sizes; Meanwhile, cutting ratio also can select other.
Embodiment two:
The present invention adopts halves to implement, schematic diagram as Fig. 4, shown in circuit diagram is as corresponding in Fig. 6.The present embodiment is cut at 156 × 156mm halves; then interconnecting strip 2 is used to connect 12pcs as a substring; two substrings carry out parallel connection and ensure to export constant with area solar array voltage, and the string group voltage of diode protection keeps consistent with traditional solar components.
Embodiment three:
The present invention adopts the quartering to implement, schematic diagram as Fig. 5, shown in circuit diagram is as corresponding in Fig. 7.The present embodiment is cut by 156 × 156mm quarter; then interconnecting strip 2 is used to connect 24pcs as a substring; four substrings carry out parallel connection and ensure to export constant with area solar array voltage, and the string group voltage of diode protection keeps consistent with traditional solar components.
Above embodiment can reach the electric current reducing sheet solar cell, reaches interconnecting strip 2 resistance that is connected with cell piece 3 to lower power consumption; Blank area simultaneously between solar cell increases, and the light from white space that battery surface accepts increases, and reaches the effect increasing solar module power; Above two kinds of incomes thus make solar module power/transformation efficiency obtain the lifting of certain amplitude.
