Qcells says it’s constructing a pilot line for perovskite-silicon tandem photo voltaic cells that may start operations later this yr in South Korea. It’s working intently with its group in Germany, the place it has already constructed one other pilot line for tandem cells.

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.”
