In 2012, the photovoltaic winter in 2012 made everyone feel the pain of the skin. The color difference problem of the components still plagued the photovoltaic person as a huge python. Here, this paper analyzes the color difference of the polycrystalline production in a phenanthrift.
Little solution. The color of the battery is mainly controlled with a floral, red and part of the yuyang film. The red film is mainly due to the low decline.
If the velor corrosion is lower than 3, the damage layer of the silicon wafer will remove it, resulting in the overall color of the PE coating. The so-called flakes are due to the high degree of phenomenal corrosion, in general, when the decault corrosion is higher than 4.5, the silicon wafer is equivalent to the polishing treatment, and the film-filled battery sheet is bright.
The grain boundary is also Obvious. For these two phenomena, the process adjustment is mainly processed, and the proportion of HNO3 and HF is ideal for process adjustment. Second, it is an increase in supervision, and the corrosion monitoring when the production control over the production and equipment is stopped.
In the production process, the technical personnel and quality inspectors should be examined many times, and the suction of suction effects are given, ensuring corrosion and suede stability. For yin and kernels, it can be divided into the following cases, one is the soaking situation, the second is that the corrosion between the various channels is deviated. The problem of immersion liquid is in the production process, and the wafer has a time difference of the liquid contact silicon wafer when the front and rear rollers and front baffle levels are entered.
Such a silicon-induced area of the surface of the liquid is bound to be higher than the regions of the contact liquid. The difference in corrosion inevitably leads to inconsistencing the surface of the silicon surface, and the PE is plated after the coating. In order to ensure the effect of the immersion, adjustment of the decont tank roller and the baffle.
Specific adjustment method: First, the baffle and the roller are re-adjusted, and the lower wheel is leveling, and the roller is reduced as possible. The baffle rises, the height of the rising to the front roller of the wafer is placed on the front rollers of the baffle, and the finger points according to the edge of the silicon, and the other side silicon wafer is more than 15 degrees, and this method is used. Can continue to increase the height of the baffle.
From the actual effect, you can ensure the soaking effect of the silicon wafer. After adjustment, the silicon solution is uniform, and the corrosion effect of the silicon wafer can be ensured. The amount of corrosion between the various channels is mainly due to the introduction process, and some old equipment has liquid pipes, but the liquid in different pipes is a pipe supply, which causes the least drug solution, resulting in a deviation of corrosion.
Some new equipment has a separate liquid pipe, which is a porous, although the individual can guarantee individual, but the water is most problematic, so the current limit device is increased to ensure that the amount of liquid is basically consistent. Such a soaking effect is guaranteed, and the deviations of each road are also solved, and the yin and kernels caused by the phenecons are completely solved.
