TOPCon (Tunnel Oxide Passivated Contact) solar cells are a mainstream high-efficiency N-type photovoltaic technology. Their core innovation lies in the rear-side passivated contact structure, which consists of an ultra-thin SiO₂ tunneling layer (~1.5 nm) and a doped polysilicon (Poly-Si) layer. This structure significantly reduces carrier recombination and improves cell efficiency, making TOPCon one of the most widely adopted advanced PV technologies.
