Multi-Crystalline Silicon Solar Celles Laser Edge Isolation

Using the LBIC technique, outstanding isolation efficiency was detected in case of Fiber Laser scribing. Measured LBIC signal ratio > 97% on wide parameters range, and >99% in best cases, are the fingerprint of nearly ideal isolation process. Extremely high isolation efficiency was as well detected in case of UV Laser process; LBIC signal ratio > 92% was routinely obtained on wide parameters range, and >98% in best cases.
