Researchers in Saudi Arabia have built an inverted perovskite-silicon tandem device with a 1 nm thick interlayer based on magnesium fluoride (MgFx). They declare it can quit voltage losses and boost power conversion performance, while preserving 95.4% of its initial performance after 1,000 hrs.

A brand-new perovskite PV cell based on titanium dioxide nanoparticles exhibits low effectiveness losses when scaled up from cell to module.
