Perovskite developer Oxford PV has set a new world record for perovskite-silicon tandem cell efficiency at 29.52%, edging out the previous record set less than a year ago by Helmholtz Zentrum Berlin. The new record has been certified by the U.S. National Renewable Energy Laboratory.| pv magazine International
The Fraunhofer Institute for Solar Energy Systems' (ISE) CalLab has confirmed the new efficiency rating. The researchers have combined semiconductors, perovskites and CIGS to produce a monolithic two-terminal tandem cell.| pv magazine International
Scientists at the Helmholtz Zentrum Berlin have taken back the world efficiency record for a perovskite/silicon tandem solar cell, achieving 29.15% with a device measuring 1cm². The record has been confirmed by Fraunhofer ISE, and according to HZB, this means that the 30% efficiency mark is within reach.| pv magazine International
The European solar research organization, Solliance announced it has achieved a 21.5% efficiency for a flexible copper indium gallium selenide (CIGS) tandem solar cell based on perovskite.| pv magazine International
Researchers in Germany have built a perovskite-organic solar cell with low interfacial losses and a high open-circuit voltage. The device achieved an open-circuit voltage of 2.15 V, a short-circuit current of 14.0 mA cm−², and a fill factor of 80%.| pv magazine International
The result was certified by Germany's Fraunhofer Institute for Solar Energy Systems’ (ISE) CalLab and included in the charts of the U.S. Department of Energy's National Renewable Energy Laboratory.| pv magazine International
The German researchers were able to improve the efficiency through a simplified production process.| pv magazine International
New Jersey lawmakers have unanimously approved legislation to remove solar permitting bottlenecks, marking a rare legislative success in the United States, as similar efforts in other states have fallen flat this year.| pv magazine International
