Abstract:
In meso-superstructured perovskite solar cells, the scaffolding layer, composed of insulating metal oxide nanoparticles, plays an important role in the loading efficiency of the perovskite layer. This communication describes 1D mesoporous silica nanoparticles that were successfully used as scaffolds to enhance the electron extraction from the perovskite absorber layer to the working electrode.
