Description

Technical Field

[0001] The invention relates to the technical field of single-crystal solar cell trough-type wet cleaning, in particular to a low-cost, fast-activation liquid wet cleaning method and device. Background Art

[0002] In this technical field, including common functional tanks such as pre-cleaning tanks, pickling tanks, alkali washing tanks, initial polishing tanks, texturing tanks, alkali polishing tanks, etc., the currently widely used mode is "liquid preparation → cleaning → batch / time fixed discharge and replenishment → liquid drainage → re-liquid preparation". The batch life of the liquid medicine tank generally ranges from 50 to 600 batches. When the batch life of the liquid medicine tank reaches the end, the concentration of reaction products and impurity pollutants in the liquid medicine gradually increases to a peak value. At this time, the liquid medicine tank can no longer work normally, and it is necessary to drain all the liquid medicine and then prepare the liquid again to ensure the normal function of the liquid medicine tank.

[0003] However, there are problems with the current model, which mainly occur in the early stage of the batch life of the liquid medicine tank. At this time, the liquid medicine has not yet been activated and the concentration of the reaction product is low, which results in the early liquid medicine tank often failing to play its 100% role, ultimately leading to poor early wet treatment effects, especially for functional tanks such as initial polishing, texturing, and alkali polishing.

[0004] For example, the liquid composition of the texturing tank is water, KOH / NaOH, and texturing additives. In the early stage of the life of the liquid tank, the concentration of silicate in the liquid is low, the solution viscosity is insufficient, and the transport process of OH- ions from the liquid to the reaction interface lacks buffering effect, resulting in poor stability of the texturing process. In the early stage of the batch life of the texturing tank, the surface uniformity of the silicon wafer is poor, and the weight loss and surface reflectivity also fluctuate greatly, which ultimately leads to a decrease in the photoelectric conversion efficiency of solar cells. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a low-cost wet cleaning method and device for quickly activating liquid medicine, which solves the problem that in the current cleaning mode, the liquid medicine tank is not activated yet in the early stage of the batch life, and the concentration of the reaction product is low, resulting in the early stage of the liquid medicine tank often failing to play its 100% role, ultimately leading to poor wet processing effects in the early stage, especially the functional tanks such as initial polishing, silk making, and alkali polishing are greatly affected.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0022] S13: using the data model to predict the batch life of the medicine in the medicine tank.

[0023] Furthermore, the S11 comprises the following steps:

[0024] S111: Acquiring cleaning condition information in the sample solution tank;

[0025] S112: determining a plurality of characteristic data dimensions according to the cleaning condition information in the sample liquid tank;

[0063] When the liquid inlet valve 5 of the liquid medicine auxiliary tank is opened, the liquid medicine tank fixed discharge valve 7 is closed synchronously, and the liquid medicine auxiliary tank 3 directly replenishes the liquid medicine of the liquid medicine tank 1 for process fixed discharge.

[0064] Preferably, S4 includes:

[0065] The liquid medicine auxiliary tank 3 is replenished in batches, with the replenishment volume of each batch being 1-10L, and the interval of replenishment is consistent with the process interval of the liquid medicine tank 1.

[0068] Preferably, the mid-term medicine solution refers to 20%-80% of the overall life of the medicine solution.

[0069] The working principle and beneficial effects of the above scheme:

[0070] The present invention solves the problem that in the early stage of the batch life of the liquid medicine tank 1, the liquid medicine has not been activated and the concentration of the reaction product is low, resulting in the early stage of the liquid medicine tank 1 often failing to play its 100% role, and ultimately leading to poor wet processing effect in the early stage, especially the functional tanks such as initial polishing, texturing, and alkali polishing are greatly affected by the mixing of the mid-term liquid medicine reserved in the liquid medicine sub-tank 3 with the new liquid medicine.

[0071] The present invention provides a low-cost wet cleaning method for quickly activating liquid medicine, and designs a new tank structure, which can automatically identify the liquid medicine in the liquid medicine sub-tank 3 for updating, realize the self-replenishment and recycling of the liquid medicine, ensure the activity and functionality of the liquid medicine, and save the cost of the liquid medicine. Thus, on the basis of existing large-scale production, the cleaning effect of the liquid medicine tank 1 in the early period of its life is improved; the tank structure is simple, easy to operate, and there is no need to adjust the process frequently; and the amount of the initial liquid medicine is reduced, so that the liquid medicine can be recycled, and the cost of the liquid medicine and the cost of waste discharge are reduced; it can be widely applied to all tank-type wet processes in the process flow of crystalline silicon solar cells, including but not limited to pre-cleaning tanks, pickling tanks, alkali washing tanks, initial polishing tanks, velvet-making tanks, alkali polishing tanks and other commonly used functional tanks.

[0072] Example 2

[0073] See also Figure 1-4 On the basis of Example 1, a single crystal texturing and cleaning method with rapid activation of liquid is provided. After the batch life of the texturing liquid tank 1 is reached, the liquid is emptied. When the liquid is prepared again, the liquid outlet valve 2 of the liquid auxiliary tank is opened, and the intermediate liquid reserved in the liquid auxiliary tank 3 is added. After the liquid reaches the working liquid level, texturing begins.

[0077] Preferably, the mid-term medicine liquid is discharged into the medicine liquid auxiliary tank 3 by controlling the medicine liquid auxiliary tank inlet valve 5 at the middle of the batch life of the medicine liquid tank 1 to supply the next liquid preparation;

[0078] Preferably, the mid-term medicine solution refers to 30%-40% of the overall life of the medicine solution;

[0079] Compared with the weight loss and surface reflectivity of each batch of single crystal silicon wafers after texturing during normal production, the weight loss and surface reflectivity of batches 1-40 using this method have increased significantly, and compared with batches 41-200, the overall fluctuation is relatively gentle.

[0080] It can be seen that the single crystal texturing and cleaning method of the low-cost fast-activation liquid of the present invention improves the texturing effect in the early stage of the texturing tank's life on the basis of existing large-scale production, makes the texturing tank more stable throughout its entire life cycle, reduces the amount of initially prepared liquid, allows the liquid to be recycled, and reduces the liquid cost and waste discharge cost.
