In my experience, the vertical lines among the blackened lines are mainly caused by broken fine grid lines; other twisted or dotted black lines are mainly caused by crystal boundaries or some pollution. The blackened area is mainly because this area causes abnormal electroluminescence for some reasons. Actually, the first answer is quite comprehensive and everyone agrees. Haha
Can cold light allow solar panels to produce electricity?

Impossible. Cold light (EL) stands for Electro Luminescent. It is a phenomenon which converts theelectrical energy into light energy. It combines a variety of substances to produce a low temperature light source that does not generate heat during operation. Solar power generation method Solar power There are two ways to produce electricity, one
