摘要：

Harvesting the sunshine : Two new pyrrole-containing organic dyes were rationally designed and easily prepared. Thanks to the special electronic properties of pyrrole moieties and the introduction of the non-coplanar aromatic rings through a single bond (blue part in the above structure), a solar-cell device based on the sensitizer LI-1 yields an overall conversion efficiency as high as 91 % of the standard cell from N719. © 2009 Wiley-VCH Verlag GmbH & Co.
