Abstract

In interdigitated back contact (IBC) solar cells, the metal-electrode coverage on a p-type emitter is optimized by a PC2D simulation. The result shows that the variation of the metal coverage ratio (MCR) will affect both the surface passivation and the electrode-contact properties for the p-type emitter in IBC solar cells. We find that when R_c ranges from 0.08 to 0.16Ω·cm², the MCR is optimized with a value of 25% and 33%, resulting in a highest energy-conversion efficiency. The dependences of both V_oc and fill factor on MCR are simulated in order to explore the mechanism of the IBC solar cells.
