Nanostructured nitrogen and carbon codoped TiO2 thin films: synthesis, structural characterization and optoelectronic properties
… The challenge with TiO2 is that the wide band gap (3.00-3.20 eV) absorbs only ultra-violet (UV) photons and only a small percentage of the solar spectrum is in the UV range. There are various ways to overcome the challenge of sensitizing the material to visible light absorption and this …
