Method for texturing silicon wafers for producing solar cells |
摘要 |
In a method for texturing silicon wafers for producing solar cells, the step of introducing a silicon wafer involves the use of a texturing solution which is at a temperature of at least 80 degrees Celsius and which comprises water admixed with 1 percent by weight to 6 percent by weight KOH or 2 percent by weight to 8 percent by weight NaOH and with a surfactant or a surfactant mixture constituting less than 0.01 percent by weight. Very economic texturing can be performed in this way.
