Stable New Sensitizer with Improved Light Harvesting for Nanocrystalline Dye‐Sensitized Solar Cells

Abstract

A new heteroleptic polypyridyl ruthenium complex (see Figure) with a high molar extinction coefficient has been synthesized. The complex is demonstrated to be a highly efficient, stable sensitizer for nanocrystalline dye-sensitized solar cells. For a newly developed dye, the achievement of 10.2 % power conversion efficiency is very encouraging.
