LA is a new process for high efficiency solar cell fabrication. The key
point of this process is choosing the proper laser to ablate on the
backside of the wafer, i.e. to remove or create windows on the
passivation layer of the wafer, optimizing the laser processing window
to improve performance of the wafer. Back side passivation reduces the
carrier recombination on the back surface and therefore effectively
raised the efficiency of solar cells.
Minimizes damages to the substrate
Higher open circuit voltage (Voc)
Excellent backside ohmic contact
