A Cheap Synthetic Route to Commercial Ruthenium N3 Dye for Sensitizing Solar Cell Applications

Abstract

Dye-sensitized Solar Cells (DSCs) Have Received Widespread Attention Owing to their Low Cost, Easy Fabrication, and Relatively High Solar-to-electricity Conversion Efficiency. Based on the Tio2 Electrode, Ruthenium Complex Dye, Liquid Electrolyte, and Pt Counter Electrode, Dscs Have Already Exhibited an Efficiency above 11% and Offer an Appealing Alternative to Conventional Solar Cells. however, until now the Commercial and Well Known Standard Dye Is the Ruthenium Complex, Namely, Cis-bis(isothiocyanato)-bis(2,2'-bipyridyl-4,4'dicarboxylato)ruthenium(II) (N3) which Has Been Widely Used around the Word. in this Article, N3 Standard Dye Was Synthesized and Characterized by Two Synthetic Routes: Grätzel’s Protocol and a One-pot Reaction from Cheap and Easily Prepared Starting Materials.
