摘要：

Dye-sensitized solar cells (DSSCs) have been fabricated based on visible-light-active titanium oxide (TiO2) heterojunction nanoparticle. DSSCs are purely based on both UV light-active anatase TiO2 photocatalyst and a visible-light-active dye. The main drawback of pure anatase TiO2 absorbance in the visible-light is inactive and the same is nullified while using visible-light-active TiO2 heterojunction nanoparticles. The photoinduced charge carrier recombination is also high in single-phase TiO2 photocatalysts. One of the solutions for this problem is the use of anion-doped TiO2 heterojunction nanostructures (anion for bandgap tuning and heterojunction for reducing charge carrier recombination). The main problem is synthesis of this kind of nano-heterojunction at low temperatures (<700 degrees C) to get good surface area and small particle size. To overcome these problems, in the present study, anion-doped TiO2 heterojunction has been synthesized at 600 degrees C for DSSC fabrication and characterized comprehensively. Anion-doped TiO2 has the capability to absorb visible light in the spectrum, so this can be applied to enhance solar cell fabrication 2013 Elsevier B.V. All rights reserved.
