Abstract
The utility model provides a flexible soft solar cell with light weight and convenient manufacture, which comprises a soft PCB board, an EVA sheet, a cell slice pack formed by a plurality of cell slices which are connected in series, an EVA sheet and a light-transmitting film, which are sequentially arranged from bottom to top and laminated, wherein a power supply pin of the cell slice pack is connected with the line of the soft PCB board. The solar cell utilizes the soft PCB board to substitutes for the traditional lower substrate material, and uses the light-transmitting film layer to substitutes for an upper cover plate, thereby not only reducing the weight of the solar cell, but also greatly increasing the softness of the solar cell and meeting the requirements of different shapes; and in addition, the manufacturing method is basically same as the technological process for manufacturing the traditional flat plate solar cell, the equipment does not require any improvement, and the promotion is easy.
Description
Technical field
The utility model belongs to technical field of solar utilization technique, specially refers to solar module.
Background technology
Present solar cell module back veneer material generally adopts polyvinyl fluoride composite membrane (TPT) or triphenyl phosphate (TPE), be flexible material, can not play any supporting role to the battery sheet, black box relies on the upper cover plate that utilizes toughened glass to make to support, cause its weight very heavy, range of application is narrower.Toughened glass also can be accomplished certain crooked radian under certain process conditions, but lamination for fear of present solar module, the degree of crook of toughened glass and radian are all very limited, and can not adjust flexibly, whenever the battery component of doing a kind of new shape all needs die sinking, the cost height is difficult to promote the use of.
The utility model content
The purpose of this utility model is to propose a kind of in light weight, easy to make, flexible solar battery flexibly.
The key of flexible solar battery of the present utility model is that the battery sheet group, EVA sheet and the light-transmissive film that form by flexible PCB plate, EVA sheet, by multi-disc battery sheet series connection back form by from the bottom to top sequence arrangement and lamination, and the power pins of described battery sheet group links to each other with the circuit of flexible PCB plate.
Described EVA is an ethylene vinyl acetate copolymer, it is by ethene (E) and vinyl acetate (VA) copolymerization and make, has good flexibility, the transparency and lustrous surface are good, chemical stability is good, and anti-aging and anti-ozone intensity is good, and is good with the miscibility of filler, painted good with processing and forming, be fit to be applied in the flexible solar battery.Above-mentioned solar cell utilizes the flexible PCB plate to replace traditional lower shoe material, and upper cover plate replaced with a kind of printing opacity rete, not only alleviate the weight of solar cell, but also made the flexibility of solar cell increase greatly, can satisfy the needs of different shaping.
Leave the gap between the adjacent edge of described adjacent battery sheet, when avoiding the battery bending, interfere between the adjacent cell sheet.
Learn through overtesting: the thickness of described flexible PCB plate is 0.3mm～2.0mm, and length can realize the flexibility of solar module greater than 100mm, is no lack of the supportive of its hardness simultaneously again.
Flexible solar battery of the present utility model can not only alleviate the weight of assembly greatly, make the weight of black box only be original about 1/10th, and can be so that battery component well adapts to the object radian of being installed, its preparation method is basic identical with the technical process of making traditional flat-plate type solar cell assembly in addition, do not need on the equipment to do any improvement, be easy to promote.
