Journal ArticleDOI
The Influence of the Ammonolysis Temperature on the Photocatalytic Activity of β-TaON
Songhak Yoon,Alexandra E. Maegli,Santhosh Kumar Matam,Matthias Trottmann,Takashi Hisatomi,Céline M. Leroy,Michael Grätzel,Simone Pokrant,Anke Weidenkaff +8 more
TL;DR: In this article, phase-pure tantalum oxynitride powders were synthesized by thermal ammonolysis of Ta2O5 powders and X-ray diffraction revealed an enlargement of the unit cell and an increase of the crystallite size.
Journal ArticleDOI
Dynamics of solubilization of naphthalene and pyrene into dodecylammonium trifluoroacetate micelles
Yoshikiyo Moroi,Tomo Morisue,Hiraku Matsuo,Hiroaki Yonemura,Robin Humphry-Baker,Michael Grätzel +5 more
TL;DR: In this paper, a photochemical probe was used to determine the rate constant for a solubilizate molecule to escape from its parent micelle, where the quencher molecules for the excited probe are located exclusively outside of the micelle.
Journal ArticleDOI
Additives, Hole Transporting Materials and Spectroscopic Methods to Characterize the Properties of Perovskite Films.
Amita Ummadisingu,Ji-Youn Seo,Marko Stojanovic,Shaik M. Zakeeruddin,Michael Grätzel,Anders Hagfeldt,Nick Vlachopoulos,Michael Saliba +7 more
TL;DR: A number of spectroscopic methods based on the UV-Vis part of the electromagnetic spectrum useful for characterizing the different perovskite material types are described in the last part of this review.
Proceedings ArticleDOI
Nanostructured Photosystems for the Generation of Electricity and Fuels from Sunlight
TL;DR: The mesoscopic oxide films have emerged as credible contenders to conventional p-n junction photovoltaic devices as mentioned in this paper, separating light absorption from charge carrier transport dye sensitized mesoscopic solar cells (DSCs).
