    Longi mentioned it achieved a 26.56% effectivity score for a gallium-doped, p-type heterojunction (HJT) photo voltaic cell and a 26.09% effectivity score for an indium-free HJT. cell, each primarily based on M6 wafers. The Institute for Photo voltaic Power Analysis in Hamelin (ISFH) in Germany confirmed the outcomes.

    Longi revealed that it achieved energy conversion efficiencies in mass manufacturing of 26.56% for a gallium-doped p-type HJT photo voltaic cell and 26.09% for an indium-free HJT cell, each are primarily based on M6 full-size monocrystalline silicon wafers. The outcomes have been confirmed by the ISFH.

    “Resolving the long-term ache level of HJT cells, Longi’s R&D crew centered on market demand and technological innovation to attain new conversion efficiencies for business gallium-doped silicon wafer, 0.44% larger than the 26.12% introduced in September this 12 months,” the corporate mentioned in an announcement.

    The Chinese language PV module maker introduced an influence conversion effectivity of 26.12% for a similar photo voltaic cell in September, and an effectivity score of 25.47% in March.

    For the indium-free HJT cells, the crew changed the normal indium-based clear conductive movie with different supplies. It claims that completely different supplies are cheaper and extra environmentally pleasant.

    “The event additionally provides a possible answer to the indium business’s reliance on large-scale mass manufacturing, signaling a means ahead for HJT to maneuver in direction of terawatt scale manufacturing ranges,” mentioned Lengthy.

    In November, Longi claimed a record-breaking 26.81% effectivity score for an unspecified HJT photo voltaic cell. As well as, the Chinese language producer recorded an effectivity of 26.5% for an n-type heterojunction photo voltaic cell in June and a 25.19% score for a p-type TOPCon photo voltaic cell in July 2021. In June 2021, it reported a 25.21% effectivity score. for an n-type TOPCon PV cell.
