Dye-sensitized-solar-cells based on calix[4]arene scaffolds†
Abstract
We report two novel systems based on calix[4]arene scaffolds with one or two D–π–A dyes for DSSCs which present good optical and photovoltaic properties as well as suitable electron lifetimes. The system (Cx-2-TPA) opens up the possibility to prepare more D–π–A branched dyes for increased light–current conversion efficiencies.
