Photocatalytic film of iron oxide, electrode with such a photocatalytic film, method of producing such films, photoelectrochemical cell with the electrode and photoelectrochemical system with the cell, for the cleavage of water into hydrogen and oxygen
TL;DR: In this article, the photocatalytic film of semiconducting iron oxide (Fe2O3) was used for the direct cleavage of water with visible light into hydrogen and oxygen.
Journal ArticleDOI
Dye Regeneration Dynamics by Electron Donors on Mesoscopic TiO2 Films
Dennis Friedrich,L. Valldecabres,Marinus Kunst,Thomas Moehl,Shaik M. Zakeeruddin,Michael Grätzel +5 more
TL;DR: In this article, the influence of different redox mediators and electrolyte constituents on charge transfer processes in dye-sensitized solar cells was studied by contactless transient photoconductance (TPC) measurements.
Journal ArticleDOI
Design, synthesis and characterization of 1,8-naphthalimide based fullerene derivative as electron transport material for inverted perovskite solar cells
Gangala Sivakumar,Alden Hermsdorff Bertoni,Hui-Seon Kim,Paulo Ernesto Marchezi,Douglas Rosa Bernardo,Anders Hagfeldt,Michael Grätzel,Shaik M. Zakeeruddin,Ana Flávia Nogueira +8 more
TL;DR: In this article, a new fullerene derivative, PC61BNI, was designed and synthesized in which [6,6]-phenyl C61-butyric acid methyl ester (PC61BM) was modified by replacing the methyl group with 1,8-naphthalimide (NI) to investigate the molecular structure modification effect on perovskite solar cell performance.
Journal ArticleDOI
Dynamics for solubilization of naphthalene and pyrene into n-decyltrimethylammonium perfluorocarboxylate micelles
TL;DR: The entry and exit rate constants of naphthalene and pyrene to and from a micelle (k+ and k-, respectively) have been determined for n-decyltrimethylammonium trifluoroacetate (DeTAPA) and pentafluoropropionate(DeTAPP) micelles by a steady-state fluorescence quenching method.
Book ChapterDOI
Photocatalytic Cleavage Of Hydrogen Sulfide And Organosulfur Compounds
TL;DR: In this article, the photocatalytic cleavage of H2S in alkaline aqueous media and mediated by irradiation of low band-gap (2.4 eV) semiconductor dispersions of CdS is described.
