In November 2022, Qcells and a bunch of European analysis establishments in Thalheim, Germany, started a four-year analysis venture to develop extra environment friendly tandem photo voltaic cells and modules.
The group established a pilot manufacturing line in Thalheim via the so-called “Pepperoni” (Pilot line for European Manufacturing of PEROvskite-Silicon taNdem modules on Industrial scale) venture.
The corporate’s mum or dad, Hanwha Options, additionally introduced plans to take a position $100 million to deploy a pilot manufacturing line for perovskite-silicon tandem photo voltaic cells at its manufacturing unit in Jincheon, South Korea, by the tip of 2024. .
“This funding in Jincheon will mark an necessary step in securing expertise management,” mentioned Qcells CEO Justin Lee. “With a world R&D community from Korea, Germany and the US, Qcells will enhance its efforts to develop high-efficiency superior tandem cells.”
Earlier this yr, Helmholtz Zentrum Berlin and Qcells in Germany offered a tandem cell with as much as 29.3% effectivity price. The outcomes have been verified by the US Division of Power’s Nationwide Renewable Power Laboratory (NREL).
The system is predicated on a silicon backside cell that depends on Hanwha Qcells’ monocrystalline Q.antum half cell expertise and a perovskite-based prime cell.
“This newest report effectivity end result, at 28.7%, is an enchancment of virtually one proportion level in comparison with the 2020 report worth of 27.8%,” the module maker mentioned in a press release. “This tandem effectivity enchancment was achieved by enhancing each the perovskite and the silicon subcells.”
