Journal ArticleDOI
Charge carrier separation and charge transport in nanocrystalline junctions
TL;DR: In this article, the fundamental problems concerning nanocryst were discussed from a mol. perspective and for example quantum chem. calcns on small TiO2 clusters can be used to describe local surface states.
Journal ArticleDOI
A novel one-step synthesized and dopant-free hole transport material for efficient and stable perovskite solar cells
Xiaoming Zhao,Fei Zhang,Fei Zhang,Chenyi Yi,Dongqin Bi,Xiangdong Bi,Peng Wei,Jingshan Luo,Xicheng Liu,Shirong Wang,Xianggao Li,Shaik Mohammed Zakeeruddin,Shaik Mohammed Zakeeruddin,Michael Grätzel +13 more
TL;DR: In this paper, a hole transport material ST1 was synthesized by a one-step Heck reaction and compared to Spiro-OMeTAD, perovskite solar cells with ST1 exhibit a remarkable overall power conversion efficiency of 15.4%.
Journal ArticleDOI
FTIR spectroscopic study of the interaction of CO2 and CO2 + H2 over partially oxidized Ru/TiO2 catalyst
TL;DR: In this article, at least three distinct linearly bound carbonyl species are identified in the adsorption of CO2 or CO2 + H2 over Ru RuO x TiO 2 catalyst.
Journal ArticleDOI
Boosting the efficiency of aqueous solar cells: A photoelectrochemical estimation on the effectiveness of TiCl4 treatment
Federico Bella,Simone Galliano,G. Piana,Giulia Giacona,Giulia Giacona,Guido Viscardi,Michael Grätzel,Claudia Barolo,Claudio Gerbaldi +8 more
TL;DR: In this article, the electrochemical and photoelectrochemical effects of the TiCl4 treatment onto TiO2 electrodes, a well-known process for traditional dye-sensitized solar cells, were investigated for the first time in water-based systems.
Journal ArticleDOI
A selective co-sensitization approach to increase photon conversion efficiency and electron lifetime in dye-sensitized solar cells.

TL;DR: The co-sensitized devices C106 + D131 showed significant enhancement in the performance, which is a marked improvement over baseline devices sensitized with either D131 or C106, and the origins of these enhancements have been systematically studied.
