Surface-reconstruction of NiOx nanocrystals makes a breakthrough in flexible solar cells

Lightweight flexible perovskite solar cells are promising for building-/vehicle-integrated photovoltaics, wearable electronics, and aerospace applications. Recently in Nature Energy, Li et al. reconstruct the surface properties of low-temperature processed NiOx nanocrystal film by tailoring a self-assembled monolayer. A record power conversion efficiency of 24.4% (certified) was achieved in flexible solar cells using an all-perovskite tandem structure.
