Web25. júl 2024 · TOPCon technology is applied to the front surface of n-type TOPCon bifacial cells. The design of the front surface cell TOPCon layer was optimized, and only the SiO 2 /poly Si passivation layer was applied to metal contact of the emitter in order to avoid parasitic absorption of sunlight by the polysilicon layer. WebWe present an industrial tunnel oxide passivated contacts (i-TOPCon) bifacial crystalline silicon (c-Si) solar cell based on large-area n-type substrate.The interfacial thin SiO 2 is thermally growth and in situ capped by an intrinsic poly-Si layer deposited by low-pressure chemical vapor deposition (LPCVD). The intrinsic poly-Si layer is doped in an industrial …
