Transition Metal Coordination Compounds as Novel Materials for Dye-Sensitized Solar Cells

Abstract

Dye-sensitized solar cells (DSSCs) are a novel solar cell alternative characterized by lower toxicity by using coordination transition metal compounds while providing high performance benchmarks, such as power conversion efficiency. Particular attention should be paid to compounds containing Cu, which can act both as dyes and as redox mediators, even though compounds relying on other transition metals are also frequently reported. In this paper, examples of compounds containing transition metals in combination with several ligands are presented, and their basic photovoltaic parameters are given.
