TL;DR: A heteroleptic polypyridyl ruthenium complex, cis-Ru(4,4'-bis(5-octylthieno[3,2-b]thiophen-2-yl)-2,2'-bipyridine)(4, 4'-dicarboxyl-2, 2'-bIPyridine)2, has been synthesized and demonstrated as a highly efficient sensitizer for a dye-sensitized solar cell
Journal ArticleDOI
Analysis of electron transfer properties of ZnO and TiO2 photoanodes for dye-sensitized solar cells.
TL;DR: This work attempts to make a one-to-one comparison of the photovoltaic performance and the electron transfer dynamics involved in DSCs, with ZnO and TiO2 as photoanodes, and reveals that at an optimal thickness ZNO exhibits photovvoltaic performances similar toTiO2, but the internal electron transfer properties differ.
Journal ArticleDOI
An alternative efficient redox couple for the dye-sensitized solar cell system.
TL;DR: A series of new cobalt complexes synthesized and evaluated as redox mediators for dye-sensitized nanocrystalline TiO(2) solar cells yielded incident photon-to-current conversion efficiencies (IPCE) of up to 80% and the one-electron-transfer redoxmediator performed best among the compounds investigated.
Journal ArticleDOI
High-conversion-efficiency organic dye-sensitized solar cells: molecular engineering on D–A–π-A featured organic indoline dyes
Yongzhen Wu,Magdalena Marszalek,Shaik M. Zakeeruddin,Qiong Zhang,He Tian,Michael Grätzel,Weihong Zhu +6 more
TL;DR: In this article, a new D-A-π-A organic dye WS-9 was derived from WS-2 by incorporating an n-hexylthiophene unit into the π-conjugation.
Journal ArticleDOI

TL;DR: One-dimensional nanowire perovskite with the mean diameter of 100 nm showed faster carrier separation in the presence of hole transporting layer and higher lateral conductivity than the three- dimensional nanocuboid crystal, indicative of more localized exciton states in nanowires.
