اطلاعات بیشترRecombination is one of the major reasons that limit solar cell efficiency. As a remedy, passivation reduces recombination both at the surface and the bulk. The field-effect passivation mitigates the surface recombination by the electric field generated by the excess doping layer or by the corona charging of the dielectric layer.
Considering that the surface structure of the back side also has a great influence on the passivation effect of PERC solar cell, another set of wafer samples with reflectivity of 35 % (by acid polishing using HNO 3 /HF mixed solution) and Al 2 O 3 layer thickness of 3 nm were prepared by the same procedure described above.
