Solliance and ECN touts 26.3% conversion efficiencies of tandem perovskite solar cell

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.
