Titanium dioxide (TiO2) and zinc oxide (ZnO) nanostructures have been widely used as photo-catalysts due to their low-cost, high surface area, robustness, abundance and non-toxicity. In this work, four TiO2 and ZnO-based nanostructures, i.e. TiO2 nanoparticles (TiO2 NPs), TiO2 nanotubes (TiO2 NTs), ZnO nanowires (ZnO NWs) and ZnO@TiO2 core-shell structures,(More)
In amorphous hydrogenated silicon carbide (a-SiC:H) based p-i-n type solar cells, the device performance is limited by various factors. Most important of which is defects in the i-layer and particularly in the p/i interface. We performed I-V measurements on amorphous solar cells in the structure p(a-SiC H)/i(a-SiC:H)/n(a-Si:H) at AM1.5. All parameters are(More)
