If you're new to PV module assembly (tabbing in particular), you're probably trying to get a feel for all the needed materials. This part is a little like getting all the materials you need to cook dinner. You need to get EVERYTHING that is required – so you don't have to go back to the store for ¼ cup of milk (or in this case, a pint of flux). In previous posts we've talked about tabbing ribbon [1, 2, 3],
as well as tabbing flux. It is important that both of these products are used during tabbing. The flux is used to remove oxides on the surface of the tabbing ribbon (the solder coating) and promote wetting to the metallization paste. Liquid flux is generally used for this application, and it is applied by dipping the ribbon into it. Feel free to email solar@indium.com to learn exactly how these products should be used in your application.
