Chinese photo voltaic module producer Longi achieved an influence conversion effectivity of 27.30% for the HBC photo voltaic cell. The Institute for Solar Energy Research (ISFH) in Germany confirmed the end result.
The new effectivity file surpasses the earlier world file of 27.09%, which was additionally set by Longi on the finish of final yr.
At the time, Longi mentioned that the end result was produced by a brand new laser graphical course of that’s cheaper than the standard high-cost photolithography course of.
“This substitute successfully reduces the price of the BC cell,” the corporate mentioned in a press release, noting that the HBC structure additionally reduces reliance on conventional indium-based clear conductive oxide (ITO). “This success drives the commercialization of HBC photo voltaic cells, with impartial mental property and value effectiveness.”
In early November, Longi introduced an influence 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 score for an unspecified heterojunction photo voltaic cell.
