AI Customer ServiceBeside, as an important parameter, the oxidation ambient can also affect the growth of BSG, which can be a protect mask in solar cell fabrication process. This paper focuses on the boron diffusion behavior based on the O 2 flow rate in industrial TOPCon solar cells fabrication.
Boron doped emitters prepared by thermal diffusion using boron trichloride (BCl3) have been adopted in N-type Tunnel Oxide Passivated Contact (TOPCon) silicon solar cells.
It has observed that, the diffusion coefficient of boron can be affected by diffusion temperature, diffusion time, substrate orientation, substrate doping concentration and the oxidation ambient [14, 15, 16] and the diffusion enhancement ratio increases as the oxidation rate increases .
Significant improvement in the passivation quality of the dual-x SiN x passivated p + emitter without bulk lifetime degradation after negative charge injection, which makes it comparable to the cell performance of a traditional Al 2 O 3 passivated boron emitter.
Figure 2 b shows the fabrication process of TOPCon solar cells: after boron diffusion, a single side etching process is performed to remove the boron diffused layer at the rear side of silicon wafers.
Boron doping has been used for p + emitter formation in N type silicon solar cells, and on the industrial, direct thermal diffusion of boron trichloride (BCl 3) or boron tribromide (BBr 3) is usually used as doping sources [7, 8, 9].
