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
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
A new model to assess the role of module temperature in PV power plant economics, developed by scientists in Saudi Arabia, finds that keeping modules cool could be an even more effective strategy to increasing energy yield than pursuing further gains in cell efficiency. The model finds that reducing module temperature by three degrees has a similar impact on energy yield to a 1% increase in conversion efficiency.| pv magazine International
