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.
