摘要：

Squarely efficient: A squaraine sensitizer (see picture) shows an outstanding power conversion efficiency of 6.74% in liquid dye-sensitized solar cells and 2.69% in solid-state dye-sensitized solar cells. The high efficiencies are related to both the bathochromic shift of the absorption maximum compared to other squaraine sensitizers, and to the presence of additional absorptions that lead to high absorptivity over much of the visible spectrum.
