6 FAQs about [Benefits of Laser Ablation of Solar Cells]

Why is laser ablation used in solar cells?

Laser ablation, due to its inherent advantages such as high precision and throughput, requires less efforts to process a variety of ablation patterns such as dots, lines, and dashes. It is favourably used for dielectric opening in Al-LBSF solar cells over methods such as lithography and mechanical scribing.

What are the benefits of laser ablation?

The esthetic and medical community is looking for an ablative laser technology that causes no adverse effect due to excessive heat around the laser hole. It also looks for more accurate laser ablation deepness and coagulation thickness This can reduce pain, leave no scars, and burns and can be applied better to dark skin.

What is laser ablation?

Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. SurClean manufactures laser coating removal and surface preparation equipment that is precise, safe and clean. We're the future of surface cleaning.

Why is femtosecond laser ablation used in solar cell processing?
