LasFocus “SolarLase-SE2000" is a PSG laser doping tool for high-efficiency solar cell production at 5000WPH. Its thermally-stable granite optics plate can house two 532nm lasers, each with its own independent beam delivery path. 

SolarLase-SE offers excellent wafer alignment capabilities as next generation high efficiency c-Si cells require ever more precise alignment than before. High-magnification cameras can detect wafer edges or marks on the wafer precisely, enabling precise overlay of laser-written patterns between two successive processing steps.

APPLICATIONS

PSG Laser Doping, Selective Emitter (SE)

Metal-Wrap-Through Laser Drilling

PERC Laser Ablation

SE process is adopted for high efficiency c-Si PERC solar cell fabrication. Laser beam interacts with the doping material (PSG layer) on wafer surface. SE Laser Doping reduces the Ohmic contact resistance, and enhances photon absorption at shorter wavelength. This process improves the solar cell open circuit voltage Voc, short circuit current Isc, and fill factor FF, therefore enables c-Si solar cell with +0.20% higher conversion efficiency. 
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.
Laser drilling method is used for high efficiency solar cell fabrication including MWT (Metal Wrap Through) and EWT (Emitter Wrap Through) processes. In order to reduce the shadowing effect of the screen printing lines on the front side, this process uses laser to drill holes and moves metal electrodes from frontside to the backside.

Laser Edge Isolation

Laser-Fired Contact

Uses lasers to reduce current leakage between anode and cathode of solar cells, including c-Si solar wafer edge isolation and MWT electrode isolation etc.The isolation line is usually placed as close as possible to wafer edges to minimize loss of sun absorbing area. 
Laser heats up local regions on the back side of a solar cell, the metallic aluminum there penetrates through the passivation layer and sinters together with the silicon substrate, forming aluminum back field and ohmic contact on the back side of crystalline silicon cells.
