Characterization of Interactions Among 3-Hydroxypropionitrile/LiI Electrolytes
Wang, Hongxia, Xue, Bofei, Hu, YongSheng, Wang, Zhaoxiang, Meng, Qingbo, Huang, Xuejie, & Chen, Liquan (2004) Characterization of Interactions Among 3-Hydroxypropionitrile/LiI Electrolytes. Electrochemical and Solid-State Letters, 7(10), A302-A305.
Solid electrolyte-based on lithium iodide (LiI) and 3-hydroxypropionitrile (HPN) for dye-sensitized solar cells (DSSCs) has been synthesized. Fourier transform infrared, ac impedance spectroscopy, and differential scanning calorimetry are employed to characterize the properties of the composite. Its conductivity increases with decreasing LiI content. Maximum conductivity of 3.1× 10–3 S cm–1 is obtained at LiI/HPN = 1:4 (molar ratio) at room temperature. Comparison on the interactions of the Li+ ions with the hydroxyl and with the nitrile groups indicates that Li+-nitrile coordination is preferential. A light-to-electricity conversion efficiency of 1.8% at AM 1.5 illumination has been obtained on a DSSC employing this electrolyte. ©2004 The Electrochemical Society. All rights reserved.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
