Could anyone suggest some articles and reliable sources about the (expensive) price of ruthenium and its complexes fabrication?

08 February 2020 1 8K Report

I'm writing and article about dye sensitized solar cells and I need a reliable source (articles, journals, books, reviews...) to base my statement (that ruthenium itself and ruthenium complexes fabrication are expensive compared to, for example, natural organic dyes obtained from plants).

Frank T. Edelmann

Dear Gabriela Epitácio, please find below an article which is available on ResearchGate. It contains a clear statement about the high price of ruthenium.
