silver ink

[boyettewhite]

is there a silver ink out there that can be bought by the diy person to retab the solar cell solder tabs that have been over heated and just vanish when soldering .? i have been saddened to throw perfectly good cells away if i could only recoat them with something to solder to.

Hi boyettewhite - Welcome to Solar Panel Talk!

Maybe one of the DIY guys will come up with something but it sounds to me like you are SOL.

this is what happens if you dont use a good solder station and carefully adjust the temperature to melt and make the solder flow quickly, Too hot or too cold you get problems. You should practice on some broken or well below spec cells first.Nothing beats practice.

yes that was the problem when i first started but now I Can solder them with no problem but it would be nice to be able to repair broken ones to with the ink .there would be many reasons to have the ink some cells come in with large chips that be reused if they had solder tabs on the chips.

There is silver conductive epoxy, but it still has high enough resistance, that you could not harvest much power from damaged cells, the epoxy costs more than a cell.

You might try this, I've used it successfully on PCBs.

Still, you could buy quite a few cells for 10.50.
