Description
Technical field
The utility model belongs to thin-film solar cells manufacturing technology field, is specifically related to a kind of multigroup Battery pack structure of thin-film solar cells.
Background technology
Along with technological progress and development in science and technology, the manufacturing technology of thin-film solar cells reaches its maturity, the large-scale industrialized production line is constantly gone into operation in the whole world, has brought huge commercial opportunities for solar cell market and application, particularly the optoelectronic integration building has been produced huge facilitation.Simultaneously, the manufacturer updates production equipment and production technology in order to enhance productivity, to reduce production costs, and constantly seeks the raw material of high performance-price ratio, constantly explore new material, new technology, make thin-film solar cells have practical commercial value and fine development prospect.
But present mature technique and thin-film solar cells product, commodity are sold with monoblock thin-film solar cell panel form, its commercial specification is very poor, have only a small amount of specification as: 600 * 1200,1100 * 1300 etc., its reason is that manufacturer mainly carries out global design and production according to the full-size that the size of the full-size of production line output and substrate is consistent.This is because for equal technology and material, size is big more, the thin-film solar cell panel area will be big more, the element cell of making in the thin-film solar cell panel is just many more, the power of veneer thin-film solar cells is just big more, corresponding production capacity is just big more, so substrate and production line production specification cooperatively interact and develop.
As everyone knows, when every thin-film solar cell panel is each element cell on making plate, just plans and designed series connection and the parallel way determined, and directly be produced in the thin-film solar cell panel in process of production.Just as known, each cell voltage is less, generally be in the mV level, and the voltage of thin-film solar cell panel 60～125V normally, Here it is, and the element cell that several are independent is together in series in thin-film solar cell panel inside, reach the requirement of design output voltage, have and how much go here and there such battery pack, will be that area can arrange how much group decides according to the size of thin-film solar cell panel, area is big more, battery pack is just many more, power is just big more, the positive pole of each the string location battery pack on the thin-film solar cell panel is connected and is connected on the anodal bus bar that links to each other of thin-film solar cell panel, the negative pole of each string location battery pack is connected on the bus bar that the cell panel negative pole links to each other, and has just formed the thin-film solar cell panel that can generate electricity.Because the connecting line and the bus bar of element cell are all finished at the thin-film solar cell panel internal production, so just can not cut apart again after every thin-film solar cell panel production is finished, even if semi-finished product before not finishing edge treated, can not be cut apart.This is because the prior art whole simple group group connection that is configured to that element cell connects on thin-film solar cell panel causes, this be configured in make the back and make in all indivisible, anyly cut apart the in-built connection that all can destroy cell group, cell group in the thin-film solar cell panel is opened circuit, and the cisco unity malfunction that becomes.Exactly because this deficiency and defective make thin-film solar cell panel in process of production, no matter be the defective in inner somewhere, damage in still outside part, and the monoblock thin-film solar cell panel is with influenced and even scrap; And because whole thin-film solar cell panel is indivisible, on building, use, particularly be applied in household solar energy system aspect, as install and use on the window that furnishes the balcony with glass walls or face south, be subjected to having a strong impact on of size and specification, cause great difficulty to marketing.
For solving the above-mentioned defective of prior art, the utility model proposes a kind of multigroup set constructor of thin-film solar cells, can on a thin-film solar cell panel, construct the element cell group that forms a plurality of different sizes, can be when the accurate finished product before semi-finished product or the edge treated, be cut into a plurality of less thin-film solar cell panels by group, also can be connected to form a monolithic film membrane solar panel and use by the outside.
Summary of the invention:
The purpose of this utility model solves the above-mentioned defective of prior art, be implemented in the element cell group of a plurality of different sizes of structure formation on the thin-film solar cell panel, can be when the accurate finished product before semi-finished product or the edge treated, be cut into a plurality of less thin-film solar cell panels by group, also can be connected to form a monolithic film membrane solar panel and use by the outside.
For this reason, the multigroup Battery pack structure of a kind of thin-film solar cells that the utility model proposes, by thin-film solar cell panel A, element cell, the plus or minus electrode, bus bar, internal connection line, line of cut and thin-film solar cell panel edge configuration form, it is characterized in that on thin-film solar cell panel A substrate size and area that existing production line adopts, element cell with its all same sizes that can make, the group that is divided into a plurality of element cells, and be arranged at least on one side edge at thin-film solar cell panel A, be connected in series or parallel by the element cell of internal connection line to each group, each group's battery has independently plus or minus electrode and bus bar, forms film solar battery module Ai.
The multigroup Battery pack structure of a kind of thin-film solar cells described in the utility model, the positive and negative electrode that it is characterized in that each film solar battery module Ai can carry out the outside at the incomplete partitioning portion of thin-film solar cell panel A and be connected, and constitutes film solar battery module Ai group.
The multigroup Battery pack structure of a kind of thin-film solar cells described in the utility model is characterised in that the spacing that leaves between each film solar battery module Ai for cutting and edge treated.
The multigroup Battery pack structure of a kind of thin-film solar cells described in the utility model is characterized in that its independent plus or minus electrode of each film solar battery module Ai is arranged on the thin-film solar cell panel edge.
Technical solutions of the utility model compared with prior art the utlity model has significant advantage and tangible beneficial effect, are mainly reflected in:
1. when not influencing original production line production efficiency, make product have many specifications and variation, enrich market, satisfy wider user's request.
2. improve to produce the qualification rate of product, meet local defect in process of production and during the product of damaging, can also partly use the phenomenon of having avoided prior art all to scrap.
