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 ...
Wiley-V C H Verlag Gmbh2017Efficient electron transfer and reduced recombination with Nd:YAG laser scribing for high-efficiency quantum dot-sensitized solar cells
Inefficient charge transfer and charge recombination are critical but challenging issues that restrict the power conversion efficiency (PCE) of quantum-dot-sensitized solar cells (QDSSCs). These issues must be addressed to boost the performance of QDSSCs. ...
Elsevier2017Influence of Ionic Liquid Electrolytes on the Photovoltaic Performance of Dye-Sensitized Solar Cells
Shaik Mohammed Zakeeruddin, Jean-David Décoppet
New binary ionic liquid electrolytes based on 1-methyl-1-butylpyrrolidinium bis(trifluromethylsulfonyl)imide, 1-butylpyridinium bis(trifluromethylsulfonyl)imide, 1-methyl-3-ethylimidazolium bis(trifluromethylsulfonyl)imide, 1-methyl-3-ethylimidazolium tetr ...
Wiley-V C H Verlag Gmbh2017Influence 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 ...
Amer Chemical Soc2016Aggregates of plasmonic nanoparticles for broadband light trapping in dye-sensitized solar cells
Metallic nanoparticles (NPs) have not been effective in improving the overall performance of the cells with micrometer-thick absorbing layers mainly due to the parasitic optical dissipation in the metal. Here, using both experiment and theory, we demonstra ...
Iop Publishing Ltd2016Effect 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 ...
Wiley-V C H Verlag Gmbh2016Molecular Engineering of Potent Sensitizers for Very Efficient Light Harvesting in Thin-Film Solid-State Dye-Sensitized Solar Cells
Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Chenyi Yi, Norman Pellet, Yelin Hu, Marcel Roland Schreier, Xiaoyu Zhang, Yi Xu
Dye-sensitized solar cells (DSSCs) have shown significant potential for indoor arid building integrated photovoltaic applications. Herein we present three new D-A-pi-A organic sensitizers, XY1, XY2, and XY3, that exhibit high molar extinction coefficients ...
Amer Chemical Soc2016Molecular gelation of ionic liquid-sulfolane mixtures, a solid electrolyte for high performance dye-sensitized solar cells
Michael Graetzel, Shaik Mohammed Zakeeruddin, Jean-David Décoppet, Thomas Moehl
Cyclohexanecarboxylic acid-[4-(3-tetradecylureido)phenyl]amide is an efficient gelator to solidify ionic liquid electrolytes. In this paper we apply this low molecular weight gelator to solidify the newly prepared sulfolane based ionic liquid electrolyte. ...
Royal Society of Chemistry2014The nature of vertical excited states of dyes containing metals for DSSC applications: insights from TD-DFT and density based indexes
Transition metal complexes, typically Ru-based complexes, are the most efficient dyes used in dye-sensitized solar cells. The absorption spectra of these molecules generally involve numerous electronic transitions, which are not equivalent for the conversi ...
Royal Soc Chemistry2014Interpretation of Optoelectronic Transient and Charge Extraction Measurements in Dye-Sensitized Solar Cells
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 ...
