The cells used in this industry are categorized into P-type and N-type based on the substrate wafer type.P-type cells are made from boron-doped P-type silicon wafers and include BSF and PERC cells.The raw material for N-type cells consists of N-type silicon wafers doped with phosphorus. Current technologies used for N-type cells include TOPCon (tunneled oxide passivated contact), HJT (intrinsic thin-film heterojunction), and IBC (intersecting back￾contact cell). N-type cells conduct electricity through electrons, and the boron and oxygen pairs cause less photoluminescence attenuation, resulting in higher photovoltaic conversion efficiency.N-type cells have clear advantages.
