Abstract
The present disclosure relates to methods and related cleaning solutions (116) for cleaning a glass substrate (10, 112), such as for removing metal ion contaminates from a glass substrate (10, 112) having a transparent conductive oxide layer (12). One method includes: providing a glass substrate (10, 112) having a transparent conductive oxide (TCO) layer (12); and exposing the glass substrate (10, 112) to a cleaning solution (116) that includes 0.5% to 5% organic acid, wherein the organic acid used includes citric acid, acetic acid, or oxalic acid.
