Natalie Flores-Díaz,Hee Won Bahng,Nikolaos Vlachopoulos,Jacques-E. Moser,Shaik M. Zakeeruddin,Michael Grätzel,Anders Hagfeldt +6 more
TL;DR: In this paper, a new tandem electrolyte composed of two redox pairs, the organic radical 2-azaadamantane-Noxyl (AZ) and the well-known redox pair [Co(bpy)3]3+/2+ was investigated in dye sensitized solar cells.
Journal ArticleDOI
High intensity simulated solar irradiation: effect on the kinetics of a methanation reaction
TL;DR: In this paper, it has been shown that the effect of the support on the reaction is not directly responsible for the quantum effect due to light absorption, but rather the energetic parameters of the reaction.
Journal ArticleDOI
Electrochemical photooxidation of carboxylates on CdS electrodes
TL;DR: In this article, photoelectrochemical oxidation of formate and of some α hydroxycarboxylate species at CdS semiconductor photoanodes was investigated, yielding carbon dioxide and hydrogen.

TL;DR: In this article, a method to determine a spatially resolved photocurrent image by voltage-dependent photoluminescence microscopy is derived from basic principles, which allows real-time assessment of the microscopically resolved local J(V) curve, the steady-state Jsc, as well as transient effects.
Journal ArticleDOI
Identifying Reactive Sites and Surface Traps in Chalcopyrite Photocathodes.
Yongpeng Liu,Maria Bouri,Liang Yao,Meng Xia,Mounir Mensi,Michael Grätzel,Kevin Sivula,Ulrich Aschauer,Néstor Guijarro +8 more
TL;DR: In this article, spectroelectrochemical and computational methods were combined to investigate a model photocathode from the promising chalcopyrite family: CuIn0.3 Ga0.7 S2.
