Abstract The Interdigitated back contact (IBC) solar cell is one of the most efficient commercial solar cells in the PV market. In order to improve the IBC solar cell efficiency, the entire solar cell structure must be well designed. The first issue is the solar cell''s doping level, including the p+ and n+ surfaces. The second is that the contact and passivation must be optimized.
