Step 2How to use "broken" cells
They are the crystalline ones that Always look broken, but if they really are,
then they have not been fully prepared for use. It is an extra challenge to
solder wires onto them but this is how I do it:
Look for the wide line on the pieces, and sort out ones that only have
thin lines. The thin line ones might be useful with Wire Glue but are
too hard to solder.
Then sort the pieces with wide lines by how big they are. They will all be
about 0.55 volts but the larger pieces make more current than the smaller
pieces and it's nice to have a panel with consistent current, especially
the one you make with the biggest pieces.
Let's save the big pieces until we learn to do the small pieces.
Strip apart a short length of stranded wire and put the now loose strands
in a small box just so you can find them and so they don't wander into another
project and cause a short circuit.
ACTUALLY another option may be to use wire-wrap wire instead of bare strands,
if you don't mind stripping the end of each piece.
The broken cells have a very thin conductive layer on the blue side and
a very rough thicker one on the other. It will be more challenging to solder
onto them than on perfect cells but this is how.
