Description
Technical field
The utility model relates to solar battery sheet production technical field, particularly relates to a kind of chain equipment transporting rail of producing for solar battery sheet.
Background technology
In the production of polycrystal silicon cell, need to pass through making herbs into wool, diffusion, wet etching, PECVD and deposit SiN
x, the step such as silk screen printing and sintering, making herbs into wool is to form up-and-down matte by the corrosion of acid or aqueous slkali at silicon chip surface, increase extinction area, reduce reflection of light rate, improve short circuit current (Isc), the final photoelectric conversion efficiency that improves battery, is the first operation that solar battery sheet is produced, its object mainly: the mechanical damage layer of 1, removing silicon chip surface; 2, remove surface and oil contaminant and metal impurities; 3, form up-and-down matte, increase extinction area, reduce reflection of light rate, improve short circuit current (Isc), finally improve the photoelectric conversion efficiency of battery.It is mainly to pass through HNO
3, the processing such as HF making herbs into wool, flushing, the flushing of KOH burn into, HF, HCl cleaning.This operation, by the silicon chip before and after corrosion is weighed to calculate the degree of depth that silicon chip is corroded, is carried out the stability of this operation of control & monitor with this.After making herbs into wool completes, spread and wet etching, wet etching be mainly erode silicon chip back side and surrounding by chemical reaction PN junction to reach object positive and back side insulation, remove positive phosphorosilicate glass layer simultaneously, be convenient to the carrying out of subsequent technique.Wet-etching technology is similar with etching device and principle.
Aborning, the equipment of making herbs into wool and wet etching is chain circulation system, mostly be four tracks to eight tracks not etc., roller is fixing in orbit, rotarily drive silicon chip and move, silicon chip passes through respectively each corrosive liquid and rinse bath by the transmission of upper bottom roller, and silicon chip enters from one end, unload from the other end, complete whole flow process.But, because roller is fixing in orbit, after each operation corrosion, can present twice or the larger impression of several roads color distortion at solar battery surface at present.This be because, silicon chip is after each corrosive liquid, roller position contacts with silicon chip, thereby affect the etching extent of this position, therefore the thickness that this position deposits in the time of subsequent deposition silicon nitride film can produce differences with other positions, thereby produce the relatively large impression of solar battery surface color distortion, affect the quality of solar cell, in order to improve the quality of solar cell, keep solar cell flat appearance without impression simultaneously, meet the needs of client to battery quality and outward appearance, the roller impression of eliminating solar battery surface is this area letter technical problem to be solved.
Specifically, in prior art, the chain circulation system that silicon chip adopts when through making herbs into wool or wet etching, transmission silicon chip devices as depicted in figs. 1 and 2, put the transmitting device that " O circle " and power transmission shaft one form silicon chip in roller position, silicon chip is unloaded from unload zone through each etching tank from equipment loading area after chemical corrosion.Due to roller and power transmission shaft one, roller is evenly arranged on power transmission shaft, when transmission, roller position on different power transmission shafts is on same level line, and position can not change, in each chemical corrosion liquid, silicon chip and roller contact are more, other position etching extent is less relatively to cause this place, in the degree difference because of silicon chip surface corrosion after subsequent silicon nitride film deposition, the silicon nitride film deposit thickness of silicon chip surface will produce difference, affect the quality of solar battery sheet, and can cause in color and have certain difference with other regions, now just there will be the roller impression of solar battery surface, quality and the outward appearance of solar battery sheet are affected.
