TiO2 modification via TiCl4 treatment has been widely used to improve the power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs), in which the effects usually attribute to the inhibition of charge recombination by barrier effect. Niobium pentoxide (Nb2O5) is considered a promising photoelectrode material for DSSCs. Here we prepared urchin-like orthorhombic Nb2O5 nanospheres consisting...
Mesoporous anatase TiO2 microspheres with interconnected nanostructures meet both large surface area and connected-structure for electron transfer as ideal nano/micromaterials for application in solar cells, energy storage, catalysis, water splitting and gas sensing. In this work, mesoporous anatase TiO2 microspheres consisting of interconnected nanoparticles were synthesized by template-free, one-step...
