We applied SiO2 nanoparticles as an alternative to mesoporous TiO2 or Al2O3 scaffolds and achieved power conversion efficiency (PCE) of up to 16.2%. Careful characterization of the effects of different scaffolds on device performance reveals that SiO2-based perovskite solar cells show much higher PCE due to the higher Voc and fill factor (FF), and the hysteresis for SiO2-based perovskite solar cell...
SnO2 nanoparticle film is directly prepared by in situ thermal calcining isopropanol solution of tin tetraisopropoxide, and is used to construct the SnO2–TiO2 junction on titanium wire substrate. The titanium wire supported SnO2–TiO2 junction is further applied to fiber-shaped dye-sensitized solar cells (FDSCs). High efficiency of 5.8% (Normal Model) and 12.4% (Diffuse Model) are achieved. Our results...
