摘要：

Here comes the sun: Three highly efficient organic sensitizers with sterically hindered fluorenyl units and planar indenothiophene derivatives were designed and synthesized (see figure). Devices based on one of these compounds, JK-303, gave overall conversion efficiencies of 8.69, 9.04, 7.27, and 5.82 % using I-/I3-, CoII/CoIII, polymer gel, and solid-state electrolytes, respectively. These efficiencies are some of the highest reported for DSSCs based on organic sensitizers. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
