Chinese language photo voltaic module producer Longi has achieved an influence conversion effectivity of 27.30% for an HBC photo voltaic cell. Germany’s Institute for Photo voltaic Vitality Analysis (ISFH) has confirmed the end result.
The brand new effectivity file beats the earlier world file of 27.09%, which was additionally set by Longi on the finish of final 12 months.
On the time, Longi stated the end result was enabled by means of a brand new laser graphical course of that prices lower than standard high-cost photolithography processes.
“This substitution has successfully lowered the price of the BC cell,” the corporate stated in a press release, noting that the HBC structure additionally minimizes the reliance on conventional indium-based clear conductive oxide (ITO). “This breakthrough has propelled the commercialization of HBC photo voltaic cells, that includes impartial mental property and cost-effectiveness.”
In early November, Longi introduced a energy conversion effectivity of 33.9% for a perovskite-silicon tandem photo voltaic cell.
It claimed the world’s highest effectivity for silicon cells in November 2022, with a 26.81% effectivity ranking for an unspecified heterojunction photo voltaic cell.
