摘要: Abstract Light scattering capability is a significant factor for high efficiency dye sensitized solar cells (DSSCs), which associated with the size and morphology of nanomaterials. Here, we reported simple hydrothermal self-assembly method to synthesize size-controlled hierarchical rutile TiO2 microspheres (MS TiO2). The as-prepared uniform dandelion-like MS were constructed single nanorod unit. Due enhanced light capability, improved electron transport reduced charge recombination, photovoltaic performance have been obtained embedded in photoanodes. resultant conversion up 9.3% has achieved, short-circuit current density (JSC) open circuit voltage (VOC) at 15.6 mA/cm2 0.79 V, respectively, significantly higher than that pure P25 film based photoanodes similar thickness (7.37%). We believe this strategy would be favor efficient DSSCs.
