Momentum builds for perovskite tandems, 25%+ efficiency achieved
Researchers from Helmholtz-Zentrum Berlin (HZB) and Oxford PV have presented a new record perovskite tandem solar cell, with a 25.2% conversion efficiency, independently verified by Fraunhofer ISE. Bernd Stannowski, from HZB presented the results this week at the World Conference on Photovoltaic Energy Conversion (WCPEC-7) in Hawaii.
EPFL produces 25.2% silicon-perovskite tandem, ‘cost competitive’ production claimed
Crystalline silicon tandem cell structures show great promise in delivering efficiencies beyond the limits of conventional c-Si. Swiss researchers claim to have gone beyond 25% with a c-Si-perovskite tandem cell structure, using what they claim is a competitive production process.
