In November 2022, Qcells and a gaggle of European analysis establishments in Thalheim, Germany, started a four-year analysis undertaking 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) undertaking.
The corporate’s guardian, Hanwha Options, additionally introduced plans to speculate $100 million to deploy a pilot manufacturing line for perovskite-silicon tandem photo voltaic cells at its manufacturing facility in Jincheon, South Korea, by the top of 2024. .
“This funding in Jincheon will mark an essential step in securing know-how management,” stated Qcells CEO Justin Lee. “With a worldwide R&D community from Korea, Germany and the US, Qcells will improve 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 fee. The outcomes had been verified by the US Division of Vitality’s Nationwide Renewable Vitality Laboratory (NREL).
The system relies on a silicon backside cell that depends on Hanwha Qcells’ monocrystalline Q.antum half cell know-how and a perovskite-based high cell.
“This newest report effectivity outcome, at 28.7%, is an enchancment of just about one share level in comparison with the 2020 report worth of 27.8%,” the module maker stated in an announcement. “This tandem effectivity enchancment was achieved by bettering each the perovskite and the silicon subcells.”
