Improved Moisture Stability of Perovskite Solar Cells Using N719 Dye Molecules

Moisture Stability In article number 1900345, Hong Lin and co-workers show that the addition of N719 dye molecules effectively alleviates the moisture sensitivity of organic perovskite materials by suppressing the water migration into the perovskite structure. It is verified by later formation of the intermediate hydrate products and decreased reaction rate of macroscopic exposition to polar solvents. With better efficiency, the long-term stability of the device is greatly boosted.
