TOPCon Series PV Modules

TOPCon (Tunnel Oxide Passivated Contact) modules utilize N-type silicon wafers as the substrate. The core technology involves depositing an ultra-thin 1–2 nm silicon oxide layer and a phosphorus-doped polysilicon layer on the rear side of the cell, forming a passivated contact structure that enhances open-circuit voltage and efficiency. Combined with advanced technologies such as SMBB, high-density encapsulation, rectangular wafers, and high-reliability encapsulant materials, these modules further improve both efficiency and reliability.

    Product Introduction 
    TOPCon (Tunnel Oxide Passivated Contact) modules utilize an N-type silicon wafer substrate. The core technology involves depositing a 1–2 nm ultra-thin silicon oxide layer and a phosphorus-doped polysilicon layer on the rear side of the cell, forming a passivated contact structure that enhances open-circuit voltage and efficiency. Combined with advanced technologies such as SMBB, high-density encapsulation, rectangular wafers, and high-reliability encapsulant materials, these modules further improve both efficiency and reliability.

    Product Advantages 
    Higher conversion efficiency, lower degradation (1% in the first year and a linear 0.4% per year), superior temperature coefficient (-0.29%/°C), and a high bifaciality rate (>80%) significantly boost power generation over the entire lifecycle. With a market share exceeding 80% and seamless collaboration across the entire industry chain, it delivers exceptional value for money, making it the undisputed king of cost‑performance among today’s module products.

    Applicable Standards 
    IEC61215 & IEC61730, UL61730

    Product Certification 
    TÜV SUD，UL，CE

    Application scenarios 
    TOPCon photovoltaic modules are widely deployed in large-scale ground-mounted solar farms—such as those located in deserts and barren lands—as well as in distributed-generation projects, including commercial and industrial rooftops and residential systems. They are also suited for specialized applications like agrivoltaics, aquavoltaics, and installations in coastal or high-altitude regions, making them the most versatile PV module technology available today.
