Description
Technical field
The utility model relates to a kind of polycrystalline solar module of the sun.
Background technology
Solar module is a kind of device due to photovoltaic effect, solar energy being converted into electric energy, is a kind of novel power supply, has permanent, spatter property and the large feature of flexibility three.But existing solar module exists that conversion efficiency is low, production cost is high, dazzle seriously waits not enough.
Utility model content
The purpose of this utility model is exactly to provide for above-mentioned situation that a kind of conversion efficiency is high, production cost is low, has the polycrystalline solar module of anti-dazzle effect.The purpose of this utility model realizes by following scheme: a kind of polycrystalline solar module, comprise solar battery sheet, the front of solar battery sheet is coated with catadioptric film, be toughened glass above catadioptric film, be EVA adhesive film and glass back plate below solar battery sheet, the composite bed that described catadioptric film is made up of hollow silica ball film and silicon oxynitride film, the composite bed formed due to hollow silica ball film and silicon oxynitride film has better optical match characteristic compared with monofilm, not only have the light of the 520nm that the principal spectrum of silicon responds and excellent subtract refraction effect, and have good refraction effect to the light of wavelength within the scope of 300-1200nm, thus improve the conversion efficiency of polysilicon solar cell, described toughened glass has towards the inner surface of cell piece side and the outer surface deviating from solar battery sheet, described outer surface is provided with the projection of several outside projections, on the outer surface that described projection is evenly arranged, also organic substance has been filled with between adjacent projection, according to sunken light principle, the light that solar module reflects can reflex on solar battery sheet by this organic substance more again, and then light reflection can not only be reduced further and go out, improve anti-dazzle effect, also can promote the absorptance of solar battery sheet, improve conversion efficiency, the inner surface of described backboard also has one deck ceramic frit layer, the thickness of described ceramic frit layer is 0.2mm, because pottery has high reflecting properties, enhance the reflection utilance to light, improve conversion efficiency, described catadioptric film printed thereon has positive electrode, described positive electrode comprises three and is parallel to each other and the main gate line of uniform intervals setting, many are parallel to each other and the identical secondary grid line of width, described main gate line and described secondary grid line intersect vertically, described main gate line is the fine line that width is greater than described secondary grid line, described fine line is arranged at intervals with the solid line segment that multiple width is greater than described fine line, the width of described solid line segment is 1.4mm, the width of fine line is 0.3mm, the width of described secondary grid line is 0.04mm, by main gate line and secondary grid line are narrowed simultaneously, namely printing slurry can be saved, reduce production cost, also shading-area can be reduced, promote conversion efficiency, the back side of described solar battery sheet is provided with three back electrodes, described back electrode is bar shaped, there are three, every root back electrode is divided into three sections, every segment length is 20-23.2mm.The back electrode of this structure
The use of printing slurry can be reduced, reduce production cost.The utility model has low cost of manufacture, conversion efficiency high.
