Specific embodiment
A kind of high transformation efficiency generating electricity on two sides photovoltaic module, includes successively from top to bottom coated glass header board 1, encapsulation front layer
2nd, layer 5, coated glass back plate 6, Split type connecting box 7 after stagewise weavy grain welding 3, N-type double-side cell group 4, encapsulation.
The coated glass header board, its plated film is double-decker, upper strata be scratch resistance automatically cleaning film 8 (film in hydrophobic or
Person's hydrophilic, pencil hardness need to reach more than 8H), lower floor is high antireflection film 9.Current market common product such as Enki companies
708/208 two-layer coating product.
The air surface plated film of the coated glass back plate is double-decker, and lower floor is reflectance coating 10, can adopt silk screen printing
Highly reflecting films (battery panel region is left white), upper strata is high antireflection film 11.
The stagewise weavy grain welding, its production technology is Copper base material 12 after extrusion forming process, forms two-sided knitting
Stricture of vagina is constructed, and its textured shape is pyramid or spherical structure.Its tin plating technique is left and right air knife in different time sections, is applied
Plus blast in regular change, so as to ensure that welding is presented the effect for thickening gradually.The stagewise weavy grain welding and battery
The part of piece main grid contact, is coated with thicker solder 13, it is ensured that welding performance；And non-contact part, relatively thin solder is only plated,
While welding is ensured, anti-oxidation function is played.
Encapsulation front layer, can adopt the light conversion encapsulation that with the addition of the light that can convert uv light into visible ray conversion particle
The form of front layer, its adding proportion is 0.1% to 2%.
Layer after encapsulation, can adopt the light conversion encapsulation that with the addition of the light that can convert uv light into visible ray conversion particle
The form of layer afterwards, its adding proportion is 0.1% to 2%.
Split type connecting box, using bypass integration module pattern, is directly worked into diode chip for backlight unit on terminal.
