The cell is based on ferrocene and is claimed to retain more than 98% of its initial efficiency after continuously operating at the maximum power point for 1,500 hours under standard illumination conditions.| 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
Developed by scientists in Saudi Arabia, the perovskite cell was able to retain over 95% of its initial efficiency after 1,000 hours at damp-heat test conditions. The cell was fabricated with a substrate made of glass and indium tin oxide (ITO), 2D layers, a 3D perovskite layer, an electron-selective layer, a buffer layer based on bathocuproine (BCP), and silver metal contact.| pv magazine International
Saudi Arabian scientists have developed a perovskite sub-cell of a tandem device with a molecule that prevents the migration of ions into the perovskite film, even under humid conditions. The solar cell has an efficiency of 28.6%.| 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
Scientists at Germany’s Fraunhofer Institute for Solar Energy Systems have broken two of their own records for cell efficiency, working with silicon and III-V material tandem cells. The institute hit 34.1% on a triple junction cell using wafer bonding technology and 24.3% by directly depositing III-V layers onto a silicon solar cell.| 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
Scientists demonstrated a perovskite-silicon tandem cell that reached 27% conversion efficiency. Though higher tandem cell efficiencies have been achieved, this represents a big jump in efficiency for those utilizing n-i-p architecture, which previously had not surpassed 22%.| pv magazine International
