Background technology
The market share of crystal silicon solar battery has accounted for more than 80% in present photovoltaic electro-optical system; And the crystal silicon solar battery flat component is mainly by solar energy ultra-white glass; Bonding agent (EVA); (as: sorting, welding, lamination, frame encapsulation etc.) produce through a series of technology for solar cell piece (monocrystalline or polycrystalline), back veneer material and aluminum alloy frame.Although the crystal silicon solar battery component price descends to some extent at present, conventional electric power costs such as same thermoelectricity, water power are compared and are still had big gap, and one of them vital factor is exactly the price of battery sheet.
The solar module majority of conventional is dull and stereotyped solar module; Adopt common planar glass to carry out printing opacity; The size of cell panel need could intactly receive solar incident ray with the big or small identical of flat glass; The consumption of battery sheet is very big, and therefore the production cost of dull and stereotyped solar module is very high.
With converging on the little battery sheet,, the consumption of minimizing battery sheet is called the condensation photovoltaic technology through optical lens thereby reducing the photovoltaic technology of system cost than the incident ray in the large area region.Present condensation photovoltaic technology mostly adopts Fresnel lens as collective optics; Like ZL200820178188.9; A kind of high concentrating solar battery assembly; The transform light energy that is used for the sun is an electric energy, and this assembly is made up of solar cell, condenser, base plate, framework, glass cover-plate and fin, is shaped as the rectangular flat shape; Fresnel Lenses is bonded on the glass cover-plate, lines up array; Solar cell is fixed on the surface on the base plate according to the arrangement mode of fresnel lens array, and solar cell can serial or parallel connection; Fin is installed in the opposite side of base plate, and with screw or heat-conducting glue fin and solar cell is linked together; Be installed in framework on the base plate with screw, then glass cover-plate bonded to the top of framework.It is collective optics that this patent adopts Fresnel Lenses; Light concentrating times is about 100～1000 times; Because the manufacturing deficiency of Fresnel Lenses surface pattern can cause the loss of a part of incident ray, cause light penetration only to be in the reduced levels about 75% on the one hand; On the other hand, Fresnel Lenses can be regarded the combination by a plurality of crown of roll lens of sharing the same light as, so light spot energy distributes even inadequately behind its optically focused; Again on the one hand because the optically focused technology must be corresponding to the sun tracker of corresponding degree of precision, and that the high more tracking accuracy to sun tracker of light concentrating times requires is high more, and system's cost of electricity-generating of therefore present condensation photovoltaic technology is still high than flat component.
If adopt common block spherical convex lens to replace Fresnel Lenses; Can solve the lower problem of light penetration to a certain extent; Therefore no matter but block spherical convex lens can only concentrate on light the focus of lens, and solar panel and lens panel how many distances of being separated by are installed, and all can cause the center and peripheral light spot energy skewness of solar panel receiving plane; Thereby cause the inner electrical potential difference of solar cell; Form internal current, this part electric current consumes at inside battery, has reduced the power output of solar cell; The generation of electric current simultaneously also must bring the rising of solar cell internal temperature, thereby has limited the useful life of solar cell.
The utility model content
The purpose of the utility model is to solve the deficiency of existing dull and stereotyped solar module and high concentrating solar battery assembly; A kind of line style collector lens solar module is provided; Overcome the classic flat-plate solar module and can not converge the sunlight incident ray to the battery sheet; The utilization ratio of battery sheet is low, shortcomings such as production cost height; The high concentrating solar battery assembly is to shortcomings such as the requirement of sun tracker tracking accuracy light spot energy skewness high, that solar cell receives weak points in even useful life.
The purpose of the utility model realizes through following technical scheme: a kind of line style collector lens solar module; It comprises line style collector lens panel, EVA adhesive film a, EVA adhesive film b, solar cell and backboard; The one side of solar cell is bonded on the line style collector lens panel through EVA adhesive film a, and another side is bonded on the backboard through EVA adhesive film b; The top of line style collector lens panel is line style arc optically focused curved array; Solar cell comprises many crystal silicon solar battery bars and welding, and the position of crystal silicon solar battery bar is vertical corresponding with the line style collector lens, and many crystal silicon solar battery bars are welded to connect on welding.
The utility model also comprises an aluminum alloy frame, and aluminum alloy frame is coated on line style collector lens solar module periphery.
The beneficial effect of the utility model is: (1) is compared with dull and stereotyped solar module; The utility model adopts line style collector lens panel to substitute the flat glass in the general dull and stereotyped solar module; Incident ray has been played the effect of effectively converging; Thereby reduced the consumption of solar cell piece, improved the utilization ratio of solar cell piece, reduced the assembly cost; (2) compare with the high concentrating solar battery assembly, the utility model is the low-concentration solar module, has reduced the requirement to the sun tracker tracking accuracy, can also effectively accomplish scale production, and has reduced the assembly cost.
