摘要：

Efficient dye-namics: A highly efficient perylene sensitizer (ν=3.8%) for solid-state dye-sensitized solar cells was obtained. Key factors for this excellent photovoltaic performance are 1) careful balance of the orbital energies and color tuning, in order to achieve a broad spectrum with high absorptivity, 2) considerate steric architecture, and 3) a sound degree of orbital partitioning. © 2011 WILEY-VCH Verlag GmbH & Co.
