Description
Technical field
The present invention relates to photovoltaic module, relate in particular to the solar module of printing opacity.
Background technology
China's energy-consuming accounts for the more than 10% of the world, and in China's primary energy consumption simultaneously, coal accounts for 70% left and right, exceeds more than 40 percentage point than world average level.The sulfur dioxide that fire coal causes and smoke discharge amount account for 70%～80% of total emission volumn, and the acid rain area that sulfur dioxide (SO2) emissions form has accounted for 1/3 of area.The aggregate level of environmental quality is also in continuous deterioration, and large city China that pollutes of the world ten occupies the majority always.Environmental pollution has brought and has had a strong impact on to Chinese society economic development and people ' s health.The World Bank estimates that the year two thousand twenty China is because environment and healthy loss that air pollution causes will reach 13% of GDP total amount.
Photovoltaic generation does not produce pollutant emission and the safety problem that traditional generation technology (for example coal fired power generation) brings, and there is no waste gas or noise pollution, there is no sulfur dioxide, discharged nitrous oxides and CO2 emission.System also seldom has the leftover problem of environmental pollution after scrapping.Solar energy is the energy that clean, reproducible, and exploitation solar energy meets national environmental protection, energy saving policy.
The electricity generating principle of photovoltaic module: solar module is arranged on above buildings, it is to utilize solar energy impinges on assembly, by the spectral absorption of solar energy above silicon cell, produce light Volta effect, in P-N knot, because negative electrical charge and positive charge have respectively been gathered in both sides, can produce an electric field that is pointed to negative electrical charge by positive charge, therefore in P-N knot, there is an electric field that points to P district by N district, form an electricity generation module.
Photovoltaic module should can Assurance component power do not reduce, consider that again production technology follows production cost, meet the requirement of indoor light transmittance.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of and not only there is solar power generation function, but also can make the solar module of the printing opacity that sunray sees through.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals.
The solar module of printing opacity, comprise solar panel, solar panel comprises solar battery sheet, the electrode of solar battery sheet interconnects by jointing, solar battery sheet top is provided with poly-vinegar ethyl ester viscose glue and toughened glass successively, solar battery sheet below is provided with poly-vinegar ethyl ester viscose glue and notacoria successively, and toughened glass and notacoria are all transparent, and the distance between adjacent two solar battery sheets is 30mm.
As preferably, toughened glass is 59%NaSiO by weight ratio
2, 9%Al
2o
3, 6%CaSiO
3, 12%K
2o, 8%CuO and 6%MgO make.Toughened glass is that simple glass is heated to, after high temperature, then after quenching, form.The toughened glass mechanical strength of making according to this ratio is high, difficult self-destruction.
As preferably, notacoria thickness is 200 μ m-350 μ m, the polyester film in the middle of comprising and the fluororesin film of both sides.At high temperature react by crosslinking agent, by fluororesin film film forming, in polyester film surface, its film forming procedure is a kind of chemical reaction process, and after film forming, trilaminate material is a gapless integrated material.
As preferably, the molecular structure of notacoria is a cross-linked structure, is connected with vinyl ethers group in described fluororesin film on the strand of fluororesin.This structures shape surperficial fluororesin film hardness high, its case hardness reaches 3H, so the resistance to marring of notacoria is better by the compound TPT material of bonding agent than trilamellar membrane.
As preferably, the peel strength of notacoria and poly-vinegar ethyl ester viscose glue is 10N/mm.Be far longer than general 3.5N/mm, ensure the good bonding performance of backboard and EVA and silica gel etc.
As preferably, the reflectivity at least 94% of notacoria.
As preferably, the lateral shrinkage of notacoria is less than or equal to 0.5%.
As preferably, the longitudinal contraction rate of notacoria is less than or equal to 1.0%.Minimum longitudinal Mechanical Contraction rate, makes to have reduced in production process the loss of back veneer material.
According to technical scheme of the present invention, the solar module of printing opacity is connected in series and is formed by many solar battery sheets, change distance between solar battery sheet sheet and sheet, distance between string and string, like this in the time that string is put, the vacancy area of adjacent cell sheet will be larger, and light shines in light by these spacing, not only had solar power generation function, but also can make sunray see through.
Brief description of the drawings
