Journal ArticleDOI
Amphiphilic Ruthenium Sensitizers and Their Applications in Dye-Sensitized Solar Cells
TL;DR: All the ligands and the complexes were characterized by analytical, spectroscopic, and electrochemical techniques and the performance of these complexes as charge-transfer photosensitizers in nanocrystalline TiO(2)-based solar cells was studied.
Journal ArticleDOI
Photovoltaic behaviour of lead methylammonium triiodide perovskite solar cells down to 80 K
Hua Zhang,Xianfeng Qiao,Yan Shen,Thomas Moehl,Shaik M. Zakeeruddin,Michael Grätzel,Mingkui Wang +6 more
TL;DR: In this article, the photovoltaic metrics of CH3NH3PbI3 perovskite solar cells over a wide temperature range from 80 to 360 K were investigated.
Journal ArticleDOI
Transparent Cuprous Oxide Photocathode Enabling a Stacked Tandem Cell for Unbiased Water Splitting
Paula Dias,Marcel Schreier,S. David Tilley,Jingshan Luo,João Lúcio de Azevedo,Luísa Andrade,Dongqin Bi,Anders Hagfeldt,Adélio Mendes,Michael Grätzel,Matthew T. Mayer +10 more
TL;DR: In this article, cuprous oxide (Cu2O) is employed as a top absorber component, and the factors influencing the balance between transparency and efficiency toward operation in a tandem configuration are studied.
Book ChapterDOI
Visible light-induced cleavage of water into hydrogen and oxygen in colloidal and microheterogeneous systems
TL;DR: In this article, a detailed analysis of methods to obtain highly active and selective catalysts, and the performance of bifunctional redox catalysts in cyclic water cleavage systems by visible light is described.
Journal ArticleDOI
Light Energy Conversion by Mesoscopic PbS Quantum Dots/TiO2 Heterojunction Solar Cells
Lioz Etgar,Thomas Moehl,Stefanie Gabriel,Stephen G. Hickey,Alexander Eychmüller,Michael Grätzel +5 more
TL;DR: The investigations showed a high resistivity for the QD/metal back contact, which reduces drastically under illumination, and a shift of the depletion layer capacitance under illumination related to the change of the dipole at this interface.
