Ion-Coordinating Sensitizer in Solid-State Hybrid Solar Cells

Sun sensitivity: A charge-transfer sensitizer with an ion-complexing moiety formed by oxyethylene side groups (see picture) is used in a solid-state dye-sensitized solar cell. Lithium coordination to the dye backbone produces under realistic conditions photovoltages of nearly 900 mV and efficiencies of 3.8%.
