Scientists in Switzerland achieved 26.5% efficiency on a perovskite-silicon tandem cell measuring 4cm² and relying on industry-standard screen-printed metallization, further demonstrating the technology’s potential for large-scale production and low-cost electricity generation.
A consortium of European research institutes has received €10.6 million in EU funding to establish pilot production of a high efficiency module concept developed by Swiss startup Insolight. The module combines high efficiency multijunction cells with a solar concentrator lens and has previously demonstrated 29% efficiency.
The renowned PV-Lab at Switzerland’s École Polytechnique Fédérale De Lausanne today announced that it has taken on the role of coordinator for the EU funded research project ‘Be-Smart’, which aims at developing a European industry for building integrated PV components.
Researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a process for depositing a perovskite layer onto a silicon solar cell, which it says has already resulted in the creation of a 25.2% efficient tandem cell.
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.
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.
A collaborative project between the U.S. National Renewable Energy Laboratory, the Swiss Center for Electronics and Microtechnology (CSEM) and the École Polytechnique Fédérale de Lausanne (EPFL) has tested a range of multi junction cells in tandem configuration, and achieved efficiencies of up to 35.9%.
Scientists at Swiss research center École polytechnique fédérale de Lausanne have published research showing how the presence of light can affect perovskite film formation. The study could result in higher efficiencies and better reproducibility in perovskite cell production.
