6" Square Single Solar Cell

NOTE: During the soldering procedure, first coat a small section of the bus bar with solder (use solder 40-60 flux core which melts at a low temperature such as 262 degrees C), then coat the strip of conductive ribbon, and then join the two solder-coated surfaces. Do not attempt to remove all of the light-absorbing coating of the bus bar as this often leads to rough cell handling and breakage.
