Researchers at Solliance and ECN have fabricated a 6 inch industrially processed c-Si cell with a perovskite top layer that is mechanically stacked using ECN’s MWT-SHJ (metal-wrap-through silicon heterojunction) design that has achieved conversion efficiencies of 26.3%. The work was published during the Silicon PV/nPV conference, in Lausanne, Switzerland.
The thin-film photovoltaics research initiative Solliance, which is focused on the commercialisation of perovskite thin-film technology, has fabricated small cells with industrially-applicable, roll-to-roll (R2R) production processes, setting a number of new conversion efficiency records.
Nanoelectronics research centre imec has taken a perovskite/silicon tandem mini-module-on-cell stack to a record 23.9% conversion efficiency, significantly exceeding its 20.2% efficiency figures reported in 2016.
