An Unsymmetrical, Push-Pull Porphyrazine for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin

An unsymmetrical, push-pull porphyrazine derivative bearing an isoindole-4-carboxylic acid moiety (TT112) is synthesized and incorporated in a dye-sensitized solar cell (DSSC). The device, which constitutes the first example of a porphyrazine-sensitized so ...

Influence of Ancillary Ligands in Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin

A review. Dye-sensitized solar cells (DSSCs) have motivated many researchers to develop various sensitizers with tailored properties involving anchoring and ancillary ligands. Ancillary ligands carry favorable light-harvesting abilities and are therefore c ...

Effect of Peripheral Substitution on the Performance of Subphthalocyanines in DSSCs

Michael Graetzel, Mohammad Khaja Nazeeruddin

A series of six new subphthalocyanines (SubPcs) bearing an ethynylcarboxyphenyl anchoring unit and decorated with a variety of substituents at the peripheral position of the macrocycle have been synthesized in order to investigate the effect of the periphe ...

Highly Stable Dye-Sensitized Solar Cells Based on Novel 1,2,3-Triazolium Ionic Liquids

Michael Graetzel, Paul Joseph Dyson, Shaik Mohammed Zakeeruddin, Hoi Nok Tsao

We describe the design and synthesis of novel low viscosity bicyclic 1,2,3-triazolium ionic liquids. These new salts are applied as nonvolatile electrolytes in dye-sensitized solar cells, affording efficiencies up to 7.07% at low light intensities, and 6.0 ...

Branched and bulky substituted ruthenium sensitizers for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Aravind Kumar Chandiran

We report on the synthesis, and photovoltaic performances of four novel Ru(II)-bipyridine heteroteptic complexes TT206-209, incorporating branched and bulkier alkyl chains compared to their linear analogues C106 and CYC-B11 previously reported. In both ser ...

Rediscovering a Key Interface in Dye-Sensitized Solar Cells: Guanidinium and Iodine Competition for Binding Sites at the Dye/Electrolyte Surface

Robin Humphry-Baker, Xiong Li, Xavier Adrian Jeanbourquin

We propose a new mechanism by which the common electrolyte additive guanidinium thiocyanate (GdmSCN) improves efficiency in dye-sensitized solar cells (DSSCs). We demonstrate that binding of Gdm(+) to TiO2 is weak and does not passivate recombination sites ...

Interpretation of Optoelectronic Transient and Charge Extraction Measurements in Dye-Sensitized Solar Cells

Xiong Li, Takeru Bessho

Tools that assess the limitations of dye sensitized solar cells (DSSCs) made with new materials are critical for progress. Measuring the transient electrical signals (voltage or current) after optically perturbing a DSSC is an approach which can give infor ...

Integration of solid-state dye-sensitized solar cell with metal oxide charge storage material into photoelectrochemical capacitor

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Lin Yang

A solid-state photo-rechargeable capacitor (photocapacitor) is obtained here by coupling a dye-sensitized solar cell and a ruthenium oxide based electrochem. capacitor. This integrated system permits direct storage of energy generated by sunlight within a ...
