Heavyweight: A series of OsII-based sensitizers are prepared and demonstrated to be suitable dyes for the fabrication of DSCs with the I−/I3− electrolyte solution. The panchromatic light harvesting capability of these sensitizers extends into the near-IR region, which is achieved by simple replacement of RuII with the more reducible and heavier OsII metal. Our results underline an attainable strategy for producing DSCs with potential industrial applications.
