WASHING ASSEMBLY AND METHOD FOR MONITORING THE PROCESS OF FABRICATING SOLAR CELLS

摘要

A method for monitoring the process of fabricating solar cells includes delivering at least one solar cell substructure to a wash chamber having a wash solution therein, such that the solar cell substructure is at least partially immersed within the wash solution. A residual material is removed from the solar cell substructure using the wash solution. A pH value of the wash solution is detected automatically while the solar cell substructure is at least partially immersed within the wash solution, via a control apparatus. The method also includes determining whether the detected pH value is at a predefined threshold pH level or within a predefined pH range for the wash solution, via the control apparatus. The pH value of the wash solution is modified automatically if the detected pH value is different from the predefined threshold pH level or different from the predefined pH range.
