Description
Technical field
The utility model belongs to the solar cell manufacture field, relates in particular to a kind of structure of ultra-thin solar battery assembly.
Background technology
Traditional fuel energy reduces day by day, and the harm that environment is caused becomes increasingly conspicuous, and the whole world also has 2,000,000,000 people to can not get normal energy supply simultaneously.In this time, the whole world has all been invested regenerative resource to sight, wishes that regenerative resource can change human energy resource structure, keeps long-range sustainable development.Solar energy forms the focus of paying attention to into people with its exclusive advantage among this.Abundant solar radiant energy is an important energy, is the energy inexhaustible, nexhaustible, pollution-free, cheap, that the mankind can freely utilize.How must be converted into the governable energy with solar energy is effective, be that present various countries expert is making great efforts the problem studied.
Utilizing solar cell that solar energy is converted to electric energy is the common method that develops solar energy at present.Present the most widely used solar cell is ultra-thin crystal silicon solar (comprising a polysilicon and monocrystalline silicon) battery, and reason is that one crystal silicon solar energy battery technology is the most ripe, and it two is that element silicon content in the earth's crust is very abundant.Crystalline silicon material is prepared into also to be needed to be packaged into solar module after the solar battery sheet and just can use.In order to save the use silicon materials, solar cell has been thinned to about 200 microns at present, also developing toward thinner direction, this makes that solar cell in use is more prone to break, and therefore encapsulating material and the technology for assembly has proposed higher requirement.
At present common ultra-thin crystal silicon solar batteries assembly basic structure schematic diagram as shown in Figure 1; solar battery sheet 2 interconnects by photovoltaic welding belt 3; EVA glued membrane 4 is as binding agent fixed solar battery sheet 2 and protection is provided; assembly surface is surface cap 1 (being generally the high printing opacity toughened glass of ultrawhite), and total is supported by backboard 5.As shown in Figure 3, solar battery sheet 2 is the array arrangement spaced reciprocally.
The method for packing of making at present the ultra-thin crystal silicon solar batteries assembly of said structure is: sorting-solar battery sheet list weldering series welding-backboard lays EVA glued membrane-stacked solar cell sheet-lay EVA glued membrane-lay surface cap-lamination-cut edge-frame up-test
By as can be seen to the analysis of structural representation, breaking for fear of solar module often needs the surface cap of thicker backboard 5 and glass material 1 to support, this makes the weight of whole assembly increase greatly, this has also brought several disadvantageous results simultaneously, the one, the cost of whole assembly increases greatly, the 2nd, the weight increase of assembly makes its application scenario significantly reduce, particularly some portable electrical power applications fields.If attenuate backboard 5 and surface cap 1 can cause the problem that modular construction intensity reduces again when carrying out ultra-thin crystal silicon solar batteries component package.
Summary of the invention
The utility model provides a kind of structure of ultra-thin crystal silicon solar batteries assembly, and its purpose is to overcome the shortcoming of prior art, and the ultra-thin crystal silicon solar batteries assembly that a kind of intensity is higher, thickness is thinner, weight is lighter is provided.
For achieving the above object, technical scheme of the present invention is:
A kind of ultra-thin crystal silicon solar batteries assembly, it comprises backboard, be laid with the EVA glued membrane on the backboard, be arranged with solar battery sheet in the EVA glued membrane spaced reciprocally, solar battery sheet interconnects with photovoltaic welding belt, be laid with surface cap on the EVA glued membrane, it is characterized in that: be provided with strengthening rib strip between backboard and surface cap, strengthening rib strip is located in the interval region between the solar battery sheet.
Above-mentioned strengthening rib strip can be located between backboard and the EVA glued membrane or be located between surface cap and the EVA glued membrane or be located in the EVA glued membrane.
The beneficial effects of the utility model are:
Owing to laid strengthening rib strip, backboard can adopt thin and lighter aluminium alloy plate, pcb board, acrylic board, TPE etc., and surface cap can adopt thin equally and lighter glass plate, transparent acrylic board, PET film etc. and can not reduce overall construction intensity.By enforcement of the present invention, the crystal silicon solar batteries component thickness reduces more than 1/2, and the weight of assembly then alleviates more than 2/3, and the production cost of component package also can reduce more than 50%.This ultra-thin crystal silicon solar batteries assembly not only can be applied in the construction of photo-voltaic power generation station, has bigger advantage and application prospect in the particularly portable photovoltaic field of power supplies of photovoltaic application product scope.
