Abstract

A method for roughening a semiconducotrr substrate of a solar cell is provided, and a solar cell manufactured by a manufacturing method including the method is also provided. The method includes the following steps: introducing a semiconducotrr substrate into a chained machine; inside the chained machine, contacting the lower surface of the semiconducotrr substrate with an alkaline fluid in the chained machine; inside the chained machine, contacting the lower surface of the semiconducotrr substrate with a second acid fluid in the chained machine; inside the chained machine, contacting the lower surface of the semiconducotrr substrate with a cleaning fluid in the chained machine; inside the chained machine, contacting the lower surface of the semiconducotrr substrate with a third acid fluid in the chained machine; and leading out the semiconductor substrate from the chained machine.
