Because of wide applications of surface-modified zinc oxide nanoparticles (ZnO-NPs) in commercial sunscreens and their easiness of being released into water, concerns have been raised over their potential effects on aquatic organisms. This study comp

Tin oxide is a promising candidate for the replacement of titanium dioxide in dye-sensitized solar cells (DSSCs), due to its excellent electron transport properties. The performance of TiO2-based DSSCs can be improved either by modifying the morpholo

Unlike TiO2-based dye-sensitized solar cells (DSSCs) where improvements in the efficiency with TiCl4 treatments are well established, there are no known treatments to improve the efficiency of ZnO-based DSSCs. Here we investigated treatments (solutio
