I'm exploring the possibility of cutting existing silicon solar cells, which are 0.2mm thick. I want to know if there's a specific type of laser that would work best for this, as it needs to cut through both metal and silicon. I'm considering either a MOPA or a UV laser. Any insights on this?

For cutting solar cells, you're on the right track with either a MOPA or UV laser. MOPA lasers provide better control over the output, which can be essential for cutting sensitive materials like silicon without causing damage. Just make sure you optimize the parameters for your specific thickness and the materials involved!
Thanks for the tip! Do MOPA lasers work well for precision cutting too?
If you're just cutting the cells and not making them from scratch, you might also want to consider scribing and snapping. It can work similarly to cutting glass and doesn’t require heavy machinery. Just be cautious with how you handle the cells to avoid cracking!
That's a good point! Do you have to pre-score them significantly?
Yeah, a shallow scribe should do the trick! Just make sure you apply even pressure when snapping.

Absolutely! They excel at precision cutting, especially with fine materials.
