Journal ArticleDOI
Novel 2 V rocking-chair lithium battery based on nano-crystalline titanium dioxide
TL;DR: In this paper, a 2 V rocking chair lithium battery with nano-crystalline TiO2 (anatase) as the negative and LiNi0.5Co 0.5O2 as the positive electrode with LiN(CF3SO2)2 + ethylene carbonate/dimethoxyethane electrolyte was studied.
Journal ArticleDOI
Brick and Mortar Strategy for the Formation of Highly Crystalline Mesoporous Titania Films from Nanocrystalline Building Blocks
Johann M. Szeifert,Dina Fattakhova-Rohlfing,Dimitra G. Georgiadou,Vit Kalousek,Jiri Rathousky,Dai-Bin Kuang,Sophie Wenger,Shaik Mohammad Zakeeruddin,Michael Grätzel,Thomas Bein +9 more
TL;DR: In this paper, a novel "brick and mortar" strategy was proposed for creating highly efficient transparent TiO2 coatings for photocatalytic and photovoltaic applications.
Journal ArticleDOI
Effects of ZnO film growth route and nanostructure on electron transport and recombination in dye-sensitized solar cells
TL;DR: In this paper, the photovoltaic performances of ZnO-based dye-sensitized solar cells (DSSCs) have been studied by comparing two different nanoparticle (NP) and two different electrodeposited (ED) nanoporous films.
Journal ArticleDOI
Ba-induced phase segregation and band gap reduction in mixed-halide inorganic perovskite solar cells
Wanchun Xiang,Wanchun Xiang,Zaiwei Wang,Dominik J. Kubicki,Xueting Wang,Wolfgang Tress,Jingshan Luo,Jingshan Luo,Jiahuan Zhang,Albert Hofstetter,Lijun Zhang,Lyndon Emsley,Michael Grätzel,Anders Hagfeldt +13 more
TL;DR: Xiang et al. show that barium unexpectedly does not incorporate in perovskite lattice but induces phase segregation and bandgap reduction and inhibits non-radiative recombination.
Journal ArticleDOI
A Ga2O3 underlayer as an isomorphic template for ultrathin hematite films toward efficient photoelectrochemical water splitting
Takashi Hisatomi,Jérémie Brillet,Maurin Cornuz,Florian Le Formal,Nicolas Tétreault,Kevin Sivula,Michael Grätzel +6 more
TL;DR: It was confirmed that a Ga2O3 underlayer was applicable to a rough conducting substrate loaded with Sb-doped SnO2 nanoparticles, improving the photocurrent by a factor of 1.4 and could push forward the development of host-guest-type nanocomposites consisting of highly-rough substrates and extremely-thin hematite absorbers.
