摘要：
The present invention relates to a method for the wet-chemical edge deletion of solar cells. An etching paste is applied to the edge of a solar cell substrate surface and after the reaction is complete, the paste residue is removed. Optionally, the substrate surface is cleaned and dried. The etching paste comprises 85% H3PO4, NH4HF2 and 65% HNO3 in a ratio in the range from 7:1:1.5 to 10:1:3.5, based on the weight.
