Abstract

Solar energy power generation battery glass panels, the package rubbing board body and spacer, the plate body from last to be the euphotic layer down in proper order, go up the EVA layer, solar wafer, lower EVA layer and backsheet layer, the euphotic layer is plane -convex face glass layer, and plane -convex face glass layer comprises according to the plane -convex face mirror that the same interval was arranged a plurality of, backsheet layer is the silicon crystal slate, makes traditional ultrawhite glass into a plurality of plane -convex face mirrors, under of the shining of normal sunlight, forms many the luminous point that holds, produces ligh energy several times big than before, makes the panel fully absorb, improves the conversion efficiency of panel.

Description

Solar power generation cell face glass

Technical field

The utility model relates to technical field of new energies, more particularly, it relates to solar power generation cell face glass.

Background technology

China is one of energy-consuming state maximum in the world, is also the big country that world energy sources produces simultaneously.With the quick growth of national economy, within 2007, total energy consumption increases to 26.5 hundred million tce(ton standard coals), increased 7.72% than 2006.In 2007, primary energy ratio is: coal accounts for 76.6%, and oil accounts for 11.3%, and natural gas accounts for 3.9%, and water power, nuclear power and wind energy account for 8.2% altogether.

Expecting 2020, China's primary energy demand is 3,300,000,000 tce, and coal supply amount is 2,900,000,000 tons, and oil is 6.1 hundred million tons；But, the maximum possible producing to coal in China in 2020 is about 2,200,000,000 tons, and the maximum output of oil also only 2.0 hundred million tons, insufficiency of supply-demand is respectively 700,000,000 tons and 4.1 hundred million tons.Obviously, will meet the needs requiring economic development for the energy, it is unrealistic for fully relying on the conventional energy resource such as coal, oil.

China's energy supply situation is that coal proportion is excessive, and environmental pressure is heavy；Energy consumption is far below world average level per capita, and energy technology falls behind, and system effectiveness is low, and product energy consumption is high, and data waste is big.China's energy supply faces a severe challenge；One is that energy decision making international environment complicates, and quickly increases Foreign Oil Resource interdependency, and two is that fossil energy sustainable supply ability meets with serious challenge.In the long run, the sustainability of China's energy resource system will be constituted a serious threat by energy resources and deliverability thereof.From the angle of energy resources, environmental protection, so high demand for energy, if it is definitely infeasible for continuing to current energy framework.Therefore, while improving efficient energetically, active development and utilize regenerative resource, particularly stock number are maximum, and being distributed most common solar energy will be China only way.

The solar panel using at present be ultrawhite safety glass, EVA, cell piece and EVA and backboard are bonded together after be laminated, this kind of solar panel has the advantages such as high permeability, high mechanical properties, high-flatness, but the conversion ratio of current solar cell is relatively low, only about 17%.

Content of the invention

The purpose of this utility model is that the conversion ratio for existing solar cell pointed in background technology is relatively low, the problem such as only about 17%, provides a kind of solar panel that can solve the problem that foregoing problems.

For realizing the purpose of this utility model, techniques below scheme solar power generation cell face glass is provided, including plate body and spacer, described plate body is followed successively by photic zone, upper EVA layer, solar battery sheet, lower EVA layer and backsheet layer from top to bottom, it is characterized in that described photic zone is plan-convex glassy layer, described backsheet layer is silicon crystal slate, and described plan-convex glassy layer is made up of by the plan-convex mirror of uniform distances arrangement several, and plan-convex mirror is circular arc type projection.

As preferably, projection thickness is 3mm, and the ratio of projection radius r and thickness h is 3:10.53.

As preferably, projection arc radius R is 20mm.

As preferably, the vinyl acetate content of described upper EVA layer and lower EVA layer is 30% ~ 33%.

The beneficial effects of the utility model: traditional ultra-clear glasses makes into multiple plan-convex mirror, under the irradiation of normal sunshine, form many storage luminous points, produce the originally several times greater light energy of ratio, make cell panel fully absorb, improve the conversion efficiency of cell panel.

Detailed description of the invention

Solar power generation cell face glass, including plate body 8 and spacer 7, described plate body 8 is followed successively by photic zone the 1st, upper EVA layer the 2nd, solar battery sheet the 3rd, lower EVA layer 4 and backsheet layer 5 from top to bottom, described photic zone 1 is plan-convex glassy layer, plan-convex glassy layer lower surface is waveform, plan-convex glassy layer is made up of by the plan-convex mirror 6 of uniform distances arrangement several, plan-convex mirror 6 is circular arc type projection, projection thickness h is 3mm, the ratio of projection radius r and thickness h is 3:10.53, and projection arc radius R is 20mm.Backsheet layer 5 is silicon crystal slate, and the vinyl acetate content of described upper EVA layer 2 and lower EVA layer 4 is 30% ~ 33%.

The utility model is not limited to the solar panel involved by above-mentioned detailed description of the invention, those skilled in the art also can make multiple change accordingly, but any is equal to the utility model or similar change all should be covered in the range of the utility model claim.
