Abstract

The invention relates to the technical field of machining, in particular to a triggering agent applicable for etching treatment of a solar cell. The triggering agent is prepared from 5 parts of polydimethylsiloxane, 5 parts of ethyl acetate, 0.5 part of alantolactone, 5 parts of methyl salicylate, 5 parts of sodium chloride and 79.5 parts of water according to the following steps of: firstly, adding 5 parts of polydimethylsiloxane, 5 parts of ethyl acetate and 50 parts of water to a vessel and stirring the mixture for 10 minutes; secondly, slowly adding 0.5 part of alantolactone and 5 parts of methyl salicylate, stirring the mixture with adding, and stirring the mixture for 10 minutes after addition is completed; and finally, adding 5 parts of sodium chloride and 29.5 parts of water at one time, thereby obtaining the triggering agent. In the triggering agent, a few amount of the alantolactone is added, so that the processing efficiency of the triggering agent can be remarkably improved; by using the triggering agent in a matching way, etching surfaces of a battery substrate subjected to surface etching and side-wall protection are uniform and consistent; with a method of addition step by step, the dissolving performance among substances can be improved, and the possibility of particle agglomeration also can be prevented.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a trigger agent suitable for the texturing treatment of solar cells. Background technique [0002] In the existing solar cell processing process, the cell substrate is first placed in a plasma processing chamber, and then the surface of the substrate is etched and the sidewall is protected to form a textured surface. However, this processing method mainly has the poor uniformity of the suede surface of the formed pyramid figure. Before surface etching and sidewall protection, spraying the trigger agent on the substrate can significantly improve the uniformity of the textured surface. Contents of the invention [0003] For the technical problems existing in the prior art, the object of the present invention is to provide a kind of trigger agent suitable for solar cell texture processing, in order to achieve the above object, the present invention adopts the follow...
