Perovskite solar cell developer Oxford Photovoltaics (PV) has produced a 1 cm2 perovskite-silicon two-terminal tandem solar cell with a verified conversion efficiency of 25.2%, through an ongoing collaboration with Helmholtz-Zentrum Berlin (HZB) and the Photovoltaics and Optoelectronics Device Group at the University of Oxford, led by Professor Snaith.
Move over pesky perovskites and old faithful intrinsic amorphous silicon as the preferred solutions for tandem-junction solar cell post crystalline-silicon PERC (passivated emitter rear cell) technology: A perennial conversion efficiency record holder and space-proven solution is back to gate-crash the party.
Nanoelectronics R&D organisation imec has been appointed as the lead to a three-year €5 million EU funded R&D program on perovskite solar cells that brings together a number of European research and commercial partners.
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.
