A highly efficient organic sensitizer for dye-sensitized solar cells

Abstract

We have synthesized a highly efficient organic dye for a dyesensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V-proportional to) = 743 mV and fill factor (ff) = 0.675.
