Dye-sensitized solar cells based on visible-light-active TiO2 heterojunction nanoparticles

OK Simya, M Selvam, A Karthik, V Rajendran - Synthetic metals, 2014 - Elsevier
Dye-sensitized solar cells (DSSCs) have been fabricated based on visible-light-active
titanium oxide (TiO 2) heterojunction nanoparticle. DSSCs are purely based on both UV light-
active anatase TiO 2 photocatalyst and a visible-light-active dye. The main drawback of pure
anatase TiO 2 absorbance in the visible-light is inactive and the same is nullified while using
visible-light-active TiO 2 heterojunction nanoparticles. The photoinduced charge carrier
recombination is also high in single-phase TiO 2 photocatalysts. One of the solutions for this …
