Description
Technical field
The present invention designs the photovoltaic field, refers in particular to a kind of solar components.
Background technology
When traditional energies such as electric power, coal, oil signal for help repeatedly, when energy problem becomes the bottleneck of restriction economic development day by day, more and more countries comes into effect " sunlight program ", the exploitation solar energy resources, seek the new power of economic development, solar energy more and more causes people's attention as a kind of reproducible new forms of energy.
Solar-photovoltaic technology belongs to high-tech, new technology, and technology is constantly reformed, but problem constantly exposes simultaneously; As shown in Figure 1, comprise backboard, EVA, battery, EVA and glass in the existing solar components; The existing structure solar components is under long-term light irradiation, especially work under 1000V external voltage situation, battery surface can accumulate negative electrical charge, and these negative electrical charges can attract positive charge to form the complex centre to battery surface, have a strong impact on the operate as normal of PN junction, cause the decay of solar cell; Wherein attenuation problem is that the solar energy industry is common, and bottleneck problem; The solar components decay can make the product of 20 years designed lives become 2 to 5 years, shortens the useful life of solar product greatly; If solar components grid-connected system harm is bigger, for example: because the assembly decay power becomes more than 100 watt by original 240 watts, this assembly can influence a whole string tens, even the operate as normal of hundreds of block assembly; Produce hot spot effect when serious, cause that product catches fire, damage this grid-connected system, even the harm national grid.
Summary of the invention
The present invention seeks to prevent the potential decay of inducing, photoinduction decay prolongs battery useful life, improves novel solar component structure and the method thereof of battery quality.
To achieve these goals existing solar battery structure is redesigned and add the light transmission medium layer, a kind of solar components, described solar components comprise 6 layers of the most basic structure at least, as shown in Figure 2, be followed successively by from bottom to up: backboard, EVA, battery, transparent dielectric layer, EVA and glass; Be not limited to 6 the most basic parts, any is the improvement that carry out on the basis with this 6 part of the present invention, optimizes to obtain novel solar component all within interest field of the present invention.
Do not add the assembly of light transmission medium layer under the situation of 1000V forward bias, power attenuation 44.36% as table 1, increases the assembly of light transmission medium layer under the situation of 1000V forward bias, power attenuation 2.32%; Do not add the light transmission medium layer assembly under the 1000V forward bias, after 100 hours, the obvious deepening of assembly in the EL picture, as Fig. 5,6; Add the light transmission medium layer assembly under the 1000V forward bias, after 100 hours, component variations is not obvious in the EL picture, as Fig. 7, and 8.
Table 1 is the power attenuation contrast of the assembly that does not add the light transmission medium layer and the assembly that increases the light transmission medium layer
Backboard in the solar components part plays protection and supporting role to the battery sheet, has reliable insulating properties, water preventing ability, resistance to ag(e)ing, and back veneer material is chemically composited materials such as gluing combined type backboard film or coating backboard film; Battery is the semiconductor device that luminous energy is changed into electric energy, and battery is single crystal battery, polycrystalline battery or hull cell semiconductor photovoltaic device; The light transmission medium layer is that block charge is assembled the formation complex centre, prevents the potential decay of inducing, and the photoinduction decay increases effects such as light printing opacity, and the thickness of printing opacity insulating material is 0.1mm-2.5mm, and this printing opacity insulating material resistivity is greater than 10
14* centimetre of ohm, printing opacity insulating material light transmittance is greater than 98%; EVA mainly is the encapsulation adhesion effect, and its main component is ethylene-vinyl acetate copolymer; 6. glass mainly has been to support, printing opacity, and wind resistance, resistance to compression is to protective effects such as assemblies; Back veneer material, battery, EVA and glass are prior art, no longer describe in detail here.
The solar components manufacture process is easy, spreads backboard as shown in Figure 2 earlier, spreads EVA at backboard, then the battery sheet that connects is layered on the EVA, according to design circuit welding battery sheet, spreads the light transmission medium layer, repave one deck EVA, with the fluid sealant encapsulation, cover glass then; Lamination frames up, testing, sorting, and last EL and outward appearance detect warehouse-in.
