Abstract

The synthesis of an Ru(II) complex derived from 4-(4-methacryloyloxymethylphenyl)-2,2:6,2 terpyridine ligand, together with its spectral and electrochemical properties, has been described. The application of this complex, which does not possess the usual anchoring groups like carboxylate or phosphate, in a dye sensitized nanocrystalline TiO2 solar cell has indicated a short circuit current of 0.252 mA, an open circuit potential of 377 mV with an overall efficiency of 3.63%. The overall conversion efficiency of the system remains stable for a long period due to the efficient electron injection into the conduction band during light absorption. The high resolution scanning electron microscopy picture reveals a three-dimensional network of interconnected nanoscale particles, while x-ray diffraction studies show that the particle size is 21 nm.

Citation countsare sourced monthly from Scopus and Web of Science® 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.
