Abstract
The utility model relates to a solar battery pack, in particular to a high-power solar battery pack. The technical scheme is that the high-power solar battery pack is composed of a piece of antireflecting film coated ultrawhite tempered glass, an EVA adhesive film, a crystalline silicon solar battery and a back plate, wherein the antireflecting film coated ultrawhite tempered glass is externally melted with the EVA adhesive film, the crystalline silicon solar battery and the back plate in sequence to form a whole; the surface of the antireflecting film coated ultrawhite tempered glass is coated with an antireflecting film; and the antireflecting film coated ultrawhite tempered glass adopts a piece of single-side coated film glass or a piece of two-side coated film glass. The utility model has the benefits that the by adopting the present monocrystalline silicon and polycrystalline silicon high-efficiency batteries and combining the film coated ultrawhite tempered glass and the higher-reflectivity TPT or PET material, the photoelectricity conversion efficiency of the solar battery pack can be improved.
Description
One, technical field:
The utility model relates to a kind of solar module, particularly a kind of high power solar module.
Two, background technology:
Solar module is an a kind of because photovoltaic effect and solar energy is converted into the device of electric energy, is a kind of novel power supply, has the advantages that permanent, spatter property and flexibility three big advantages and solar module life-span grow.It is the overall structure that forms rigidity by low iron ultrawhite toughened glass, EVA glued membrane, crystal silicon solar energy battery array and backboard fusion under certain temperature, pressure and vacuum condition, bonding.Consider the result of use of solar module reality, unit are power output has become estimates one of photovoltaic module important parameter.Consider the raw-material shortage of polysilicon simultaneously and reduce production costs the necessary electricity conversion that improves solar module, i.e. high efficiency solar cell assembly on existing technical foundation.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of high power solar module is provided, and improves the electricity conversion of solar module.
Its technical scheme is: be made of coated with antireflection film ultrawhite toughened glass, EVA glued membrane, crystal silicon solar energy battery, backboard, fusion EVA glued membrane, crystal silicon solar energy battery, EVA glued membrane and backboard form integral body to described coated with antireflection film ultrawhite toughened glass successively outward, the surface of described coated with antireflection film ultrawhite toughened glass is coated with antireflective coating, adopts coating single side or double-sided coating glass.
Above-mentioned backboard adopts TPT or PET material to make, and composite surface has higher surface reflectivity.
Above-mentioned crystal silicon solar energy battery adopts monocrystaline silicon solar cell or polysilicon solar cell battery.
The beneficial effects of the utility model are: adopt present monocrystalline silicon and polysilicon high efficiency battery, in conjunction with plated film ultrawhite toughened glass and have high reflectance TPT or the PET material, improve the electricity conversion of solar module.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is that light of the present utility model is propagated schematic diagram.
Five, embodiment:
With reference to accompanying drawing 1, the utility model is made of coated with antireflection film ultrawhite toughened glass 1, EVA glued membrane 2, crystal silicon solar energy battery 3, backboard 4, described coated with antireflection film ultrawhite toughened glass 1 outer fusion EVA glued membrane 2 successively, crystal silicon solar energy battery 3, EVA glued membrane 2 and backboard 4 form whole, the surface of described coated with antireflection film ultrawhite toughened glass 1 is coated with antireflective coating, adopts coating single side or double-sided coating glass; Above-mentioned crystal silicon solar energy battery 3 adopts monocrystaline silicon solar cell or polysilicon solar cell battery, and ethylene-vinyl acetate copolymer is called for short EVA.
With reference to accompanying drawing 2, in conjunction with the propagation path of light in assembly, specifically analyze the relation of being correlated with between the material therefor from optical angle, when light saw through certain transparency medium, three kinds of situations are arranged: 1. a part was reflected; 2. pass through after the part refraction; 3. absorbed by medium.The ultrawhite toughened glass of coated with antireflection film is exactly the technology that adopts the system film on ultra-clear glasses, comprise gimmicks such as spraying plating, immersion plating, sputter, at the nanometer rete of glass surface (single or double) formation certain thickness and refractive index, film material is generally silicon dioxide or titanium dioxide.Thereby can effectively reduce the light transmittance that reflection of light improves glass, to reach the power output that improves assembly.
Part light is by assembly backboard 4 reflected back lower glass surface, form repeatedly the absorption of light, so back veneer material that adopts the surface to have high reflectance, as TPT or PET etc., can further improve the absorption of solar cell to light, wherein, TPT is meant the polyvinyl fluoride composite membrane, and PET is meant PETG.
