6 FAQs about [Ibc Main process steps of solar cells]

How does IBC solar cell fabrication work?

However, IBC solar cell fabrication involves complex patterning steps for the interdigitated rear structure. Furthermore, since both contacts are on the rear side, the fabrication process must ensure low recombination at the surfaces.

What is a digitated Back Contact (IBC) solar cell?

Due to the interdigitated back contact (IBC) solar cell design, no optical shading occurs at the front side of the cell comparing to the standard front / rear contacted cell design, which has current loss due to the front metal grid , . With the hetero-junction IBC structure, a record cell efficiency of 25.6% was achieved .
