Perovskite photovoltaics

Barrier layer for space

Perovskite solar cells hold potential for space applications yet they need to withstand harsh space stressors. Now, researchers develop a low-cost and lightweight barrier layer of silicon oxide thermally evaporated atop the finished solar cell that affords protection against proton radiation, atomic oxygen and alpha particles.
