Abstract
Correction for ‘Dye-sensitized solar cells based on organic dyes with naphtho[2,1-b:3,4-b′]dithiophene as the conjugated linker’ by Xiaoxu Wang et al., J. Mater. Chem. A, 2013, 1, 13328–13336.
This paper is not the first time the naphtho[2,1-b:3,4-b′]dithiophene is used as the π-spacer for metal-free organic dyes in dye-sensitized solar cells (DSSCs), therefore, the words “for the first time” in the abstract of this paper should be deleted. Prior to this paper, organic sensitizers based on naphtho[2,1-b:3,4-b′]dithiophene were reported in “Embedding an electron donor or acceptor into naphtho[2,1-b:3,4-b′]dithiophene based organic sensitizers for dye-sensitized solar cells”.1 In ref. 1, naphtho[2,1-b:3,4-b′]dithiophene was used as the π-spacer, methoxy triphenylamine was used as the electron donating group, and cyanoacrylic acid was used as the electron-withdrawing anchoring moiety. Additionally, an auxiliary electron-donating group, such as 3,4-ethylenedioxythiophene (EDOT), or an electron-withdrawing group, such as benzothiadiazole was incorporated in the sensitizers reported in ref. 1. DSSCs based on the sensitizers in ref. 1 displayed high efficiency and excellent stability. Our paper reported syntheses of a series of organic dyes using naphtho[2,1-b:3,4-b′]dithiophene as the π-conjugation linker, with carbazole or triarylamine as the electron donor group and cyanoacrylic acid as the electron-withdrawing anchoring moiety. Dyes with two naphtho[2,1-b:3,4-b′]dithiophene groups as the extended π-spacer were also reported in our paper.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
