I got a bunch of individual solar cells off of E-Bay.
Several appear to have a screen printing defect on the back of the cells, leaving somewhat of a gap of the conductive material, and presumably less area to pick up the electricity on the back.
Is there an easy, cheap, high temperature, conductive paint that could be used to repair these cells? Spray Can? Automotive paint sprayer?
Perhaps I should attach the electrodes first, then repaint the back of the cells.
