What is the difference between tabbed and untabbed solar cells for a solar panel?
I’m building a solar panel for my science fair project and it has to be high school level. On ebay they have solar cells that say they are tabbed and ones that say they are untabbed. If I buy ones that are untabbed how do i “tab” them?
One has a means of attaching leads, or has leads for your electrical connection and the other you have to fabricate a means of making a connection to your cell’s conductive strips.
Depending on the amount of current the cell is to produce at peak will be your limiting factor, but something as simple as conductive tape (adhesive RF shielding for example) can work. Securing it could be done if you install them in a rabbeted frame to accept the panel and locate your conductive foil at each pole of the cell. Then a simple matter of securing a brass screw through that conductive tape with a simple wire loop under the head of the screw makes for a simple secure connection. While you could try to attach wire with a low wattage soldering iron, there are some instances where the cell could be damaged from the heat application.
Since it sounds like your cells will not be weather resistant, you will need to make a weather resistant frame for them, which makes the above a very simple method of attachment. .
