Synova - Model MCS 500 - Metal Cutting System - Brochure

The efficiency of solar cells can be increased by locally diffusing dopant underneath the front contacts, so-called selective emitters. Laser Chemical Doping uses a laser beam to groove, if necessary, the passivation layers and a chemical jet, in which the laser beam is guided, that simultaneously introduces local doping at the surface of the silicon wafers. Thin selective emitters can be produced with a laser-based industrial process. A manual loading Laser Chemical Doping system is now available from Synova. Targeting development and test laboratories, it offers a unique blend of flexibility and freedom to tailor the Laser Chemical Doping process to one’s specific solar cell structure.
