A dopant-free spirobi[cyclopenta[2,1-b:3,4-b′]dithiophene] based hole-transport material for efficient perovskite solar cells
Marius Franckevičius,Amaresh Mishra,Franziska Kreuzer,Jingshan Luo,Shaik M. Zakeeruddin,Michael Grätzel +5 more
TL;DR: In this paper, a promising hole transporting material (HTM) using the 4,4′-spirobi[cyclopenta[2,1-b:3,4-b′]dithiophene derivative (spiro-CPDT) as the core and triarylamines as terminal units was presented.
Journal ArticleDOI
Decomposition of organophosphorus compounds on photoactivated TiO2 surfaces
TL;DR: In this paper, a mechanism of degradative oxidation on the TiO2 particles involving epoxidation by surface peroxo species and direct hole oxidation is proposed, which enhances dramatically the rate of catalytic activity by inhibition of the electron and hole back-reaction as well as direct oxidation of the substrate species by the strong oxidants themselves.
Journal ArticleDOI
Resonant photoemission of anatase TiO2 (101) and (001) single crystals
Andrew G. Thomas,Wendy R. Flavell,A. R. Kumarasinghe,A. K. Mallick,D. Tsoutsou,G. C. Smith,R. L. Stockbauer,S. Patel,Michael Grätzel,R. Hengerer +9 more
TL;DR: In this article, the resonant behavior of anatase (101) and (001) surfaces has been investigated using synchrotron photoemission spectroscopy, and the results show good general agreement with bulk band-structure calculations.
Journal ArticleDOI
Merocyanine Aggregation in Mesoporous Networks
TL;DR: In this paper, mesoscopic hydroxylated anatase films were used as hosts for the merocyanine 3-acetyl-5-(2-(3-ethyl-2-benzothiazolidinylidene)ethylidene), rhodanine (Mc2) to scrutinize templating effects in the accommodation of the dye within their porous network.
Journal ArticleDOI
Room‐Temperature Formation of Highly Crystalline Multication Perovskites for Efficient, Low‐Cost Solar Cells
TL;DR: A room-temperature perovskite material yielding a power conversion efficiency of 18.1% (stabilized at 17.7%) is demonstrated by judicious selection of cations, showing great potential for low-cost, large-scale manufacturing such as roll-to-roll processing.
