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
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
The European Solar Test Installation (ESTI) has confirmed the results of King Abdullah University of Science and Technology’s (KAUST) new perovskite/silicon tandem solar cell. The 1 cm2 device also achieved an open-circuit voltage of 1.974 V, a short-circuit current density of 20.99 mA/cm2, and a fill factor of 81.3%.| pv magazine International
