Hi asp, sec!
I bought 300 "Class/Grade A" solar cells [1]. Just when I wanted to
resell some of them I discovered that most of them (all that I checked)
have a few (about 2-6) complete or partial gaps in the finger traces
that pick up the electricity and forward it to the bus bars. There are
also marks on the edge that look like overheated spots:

Many of the gaps appear in sequential cells in the same position, so...
solar cell defects?
