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 ETI-W heat pump, with a coefficient of performance of up to 4.1, utilizes heat emitted from factory production processes as a heat source to supply hot water at up to 90 C. Debuting on the Japanese market, the system targets industrial and commercial applications.| pv magazine International
