Description
Technical field
The utility model relates to solar cell package material technology field, the zinc-plated copper strips of particularly a kind of solar module.
Background technology
Solar energy is a kind of radiant energy, and it must just can convert electric energy to by means of energy converter, this transform light energy is become the energy converter of electric energy, is exactly solar cell.The structure of monocrystaline silicon solar cell is as shown below, and it is a large-area semiconductor PN, and upper surface is a sensitive surface, is coated with the main grid line electrode of the broad that the aluminium ag material makes and the thin grid line that collected current is used; The back side is similarly the aluminium ag material and makes aluminium back of the body field and backplate, and upper/lower electrode is all burn-on lead as going between with power output.In order to reduce silicon chip surface, on battery surface, be coated with the antireflective coating of one deck silicon nitride or other materials to reflection of incident light.
Battery design workers have carried out design reasonable, meticulous, science according to a series of formula and actual conditions to each part of battery, finally make the power output of battery reach peak.The output current of battery sheet is directly proportional with the light intensity and the light-receiving area of incident light, with the monocrystaline silicon solar cell is example, each chip size be the open circuit voltage of 125*125 battery sheet about 0.5V, short circuit current is about 5A, promptly the power of each sheet battery sheet is about 2.5W.
As can be seen, the electric current of each sheet battery sheet and voltage are all very low, and in actual applications, needed voltage is several hectovolts or goes up kilovolt, electric current also is different with the difference of electricity generation system, therefore, the battery sheet be used on a large scale, single battery sheet must be together in series or parallel, make the electric current of its output and the requirement that voltage satisfies electricity generation system.
At present, single battery sheet is realized that mechanical connection and the material that is electrically connected are zinc-plated copper conductor (claiming welding again), domestic basically each welding manufacturer production welding technology is very ripe, can produce according to requirement of client.
As mentioned above, the output current of battery sheet is directly proportional with the light intensity of incident light and the area of sensitive surface, if the light intensity of incident light is certain, then the output current of battery sheet only is directly proportional with the area of battery sheet sensitive surface; Yet under the situation that does not change battery chip architecture and manufacturing process, it is fixing that its sensitive surface also is tending towards.
In fact, the main grid line of battery sheet has occupied bigger a part of area on the battery sheet, and the existence of main grid line has reduced the sensitive surface of battery sheet, but the main grid line can exist; What be connected with the main grid line at present is that the welding surface is smooth flat, and the sunlight that incides on the welding all is reflected fully, can not utilize this part sunlight fully, causes having lost part power after the encapsulation of battery sheet.
Summary of the invention
The purpose of this utility model provides the zinc-plated copper strips of a kind of solar module,
The technical solution of the utility model is:
The zinc-plated copper strips of a kind of solar module comprises the planar band of bottom, and wherein: planar band is provided with some projectioies.
The zinc-plated copper strips of a kind of solar module, wherein: projection is a zigzag.
The zinc-plated copper strips of a kind of solar module, wherein: the cross section of projection is a triangle.
The zinc-plated copper strips of a kind of solar module, wherein: the angle of triangle and planar band is 45 ° ± 3 °.
The zinc-plated copper strips of a kind of solar module, wherein: the angle of triangle and planar band is 45 °, leg-of-mutton drift angle is 90 °.
Advantage of the present utility model: the utility model is simple in structure, the mode that the structure of increase zigzag fashion, employing mount on upper surface effectively is connected with the battery sheet, mount conveniently, can effectively reduce the total reflection of incident light, increase the refraction again of incident light, the battery sheet can be accepted more sunlight in limited area, therefore, can significantly improve the packaging efficiency of battery component.
