Researchers in Saudi Arabia have built an inverted perovskite-silicon tandem device with a 1 nm thick interlayer based on magnesium fluoride (MgFx). They claim it can stop voltage losses and increase power conversion efficiency, while retaining 95.4% of its initial efficiency after 1,000 hours.| 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
