Ruthenium Dye Spectroscopic and Photovoltaic Performance Data

A series of novel ruthenium dyes designed for solar energy conversion, featuring C^N^tBu donor motifs with N-heterocyclic carbene ligands. The dataset includes measurements of absorption up to 790 nm, molar absorptivity of 84,200 M–1 cm–1 at 500 nm, excited-state lifetimes of 212–210 ns, and device power conversion efficiencies up to 7.09%.

Use Cases

• Predict power conversion efficiency from dye structural features like the N-heterocyclic carbene type and acceptor functionalization.
• Analyze the correlation between excited-state lifetime (212–210 ns) and photocurrent density (25 mA cm–2) for different dye variants.
• Model the relationship between molar absorptivity (84,200 M–1 cm–1 at 500 nm) and absorption spectra up to 790 nm.
• Benchmark new dye designs against the reported Ru2+/3+ oxidation potential (0.66 V below I–/I3–) and efficiency exceeding N3/N749 benchmarks.

Strengths

• Reports specific, high-performance metrics including power conversion efficiency up to 7.09% and photocurrent density of 25 mA cm–2.
• Includes detailed spectroscopic data such as molar absorptivity of 84,200 M–1 cm–1 and absorption extending to 790 nm.
• Provides precise chemical synthesis and characterization details for a novel series of ruthenium dyes.

Limitations

• The dataset is very small at 84.0 KB, indicating limited scope and likely a small number of synthesized dye compounds.
• The specific number of data rows, columns, and sample measurements is unknown from the provided description.
• Data is from a single, specific research study, limiting generalizability to other dye classes or synthesis conditions.
