Abstract
A track for a fritting furnace of a crystalline silicon solar cell comprises a cell plate, thimbles and the continuous track. The thimbles are welded on the track. The cell plate is clamped between the thimbles and is contacted with the thimbles, and the cell plate is not directly contacted with the track. A crystalline silicon cell is supported by the thimbles on the upper portion of the track, thereby being capable of effectively improving the heating area of silicon wafers and enabling the silicon wafers to be heated evenly.
Description
Technical field
The utility model relates to a kind of crystal silicon solar energy battery sintering furnace, particularly a kind of crystal silicon solar energy battery sintering furnace crawler belt.
Background technology
Crystal silicon solar energy battery is the solar cell based on silicon materials.Crystal silicon solar energy battery positive and negative electrode and back of the body electric field will play the electric energy that silicon solar cell is produced and send extraneous effect to.Electrode and back of the body aluminium field (being mainly silver-colored slurry, aluminium paste, silver-colored aluminium paste) form by printing, oven dry, sintering.Wherein sintering process will produce bigger influence for the quality of printing back product.
During conventional solar cell is produced, the battery sheet is after the process silk screen printing, the battery sheet directly enters sintering furnace by the sintering furnace crawler belt and carries out sintering, owing to have temperature difference between sintering furnace crawler belt space, cause battery sheet local heating inhomogeneous easily, when the battery sheet directly contacts with crawler belt, the local temperature that contacts with crawler belt is not enough, if crawler belt directly contacts with positive silver-colored face, easily cause the disconnected grid of contact point and do not form good Ohmic contact, thereby influence series resistance.Thereby, crawler belt influences the battery piece performance if contacting with aluminium back of the body field then can cause bulge or the crawler belt seal occur.
The utility model mainly comprises the improvement of sintering furnace crawler belt, and conventional sintering stove crawler belt mostly presents network structure, when the crystal silicon cell sheet directly contacts with crawler belt, owing to have temperature difference between the crawler belt space, is heated inhomogeneous easily and causes sintering bad.On the basis of crawler belt, thimble is welded to the both sides of crawler belt, weld two thimbles respectively in the both sides of crawler belt, thimble and horizontal plane have certain gradient, and the battery sheet only has any to contact with single thimble, can effectively improve the battery sheet and contact the bad problem of sintering with crawler belt.
The utility model content
The purpose of this utility model is for a kind of crystal silicon solar energy battery sintering furnace crawler belt is provided, to solve the shortcoming in the background technology.
A kind of crystal silicon solar energy battery sintering furnace crawler belt, comprise battery sheet, thimble, crawler belt, on crawler belt, weld thimble, the battery sheet will be stuck between the thimble, the battery sheet contacts with thimble, and the battery sheet will directly not contact with crawler belt, by the thimble support crystal silicon cell sheet on crawler belt top, can effectively increase the heating surface area of silicon chip, it is heated evenly.
Beneficial effect:
The utility model patent simplicity of design, be easy to make,, can effectively solve the bad battery performance decline problem that causes of the sintering that in actual production process, occurs, thereby effectively improve the solar cell transformation efficiency with respect to traditional crawler belt.
Description of drawings
Accompanying drawing 1 is the utility model design diagram.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of crystal silicon solar energy battery sintering furnace crawler belt, as shown in Figure 1, the utility model comprises battery sheet 1, thimble 2, crawler belt 3, welding thimble 2 on crawler belt 3, battery sheet 1 will be stuck between the thimble 2, and battery sheet 1 contacts with thimble 2, battery sheet 1 will directly not contact with crawler belt 3, thimble 2 by crawler belt 3 tops supports the crystal silicon cell sheet, can effectively increase the heating surface area of silicon chip, and it is heated evenly.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
