New sensitizers for dye-sensitized solar cells featuring a carbon-bridged phenylenevinylene

Abstract

We demonstrate that a carbon-bridged phenylenevinylene (CPV)-linked dye serves as a novel and efficient sensitizer for dye-sensitized solar cells. The cells show IPCE values of greater than 90%, PCEs of up to 7.12%, and high open circuit voltages reaching close to 0.8 V based on the iodide/triiodide electrolyte. © The Royal Society of Chemistry.
