Bis-2'-hydroxychalcone and its Complexes as Potential Dye Sensitizer for Dye-sensitized Solar Cell Application

In this study, the power conversion efficiency of bis-chalcone derivatives and its complexes as the dye sensitizer in dye-sensitized solar cell had been determined. A total of 6 compounds of bis-chalcone derivatives, namely, compound 1A, 1B, 2A, 2B, 3A and 3B had been synthesized by the Claisen-Schm...
