D-pi-A Dye System Containing Cyano-Benzoic Acid as Anchoring Group for Dye-Sensitized Solar Cells

Michael Graetzel, Guido Rothenberger, Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Takeru Bessho, Efthimios Kaxiras, Sheng Meng

A D-pi-A dye (KM-1) incorporating cyanobenzoic acid as a new acceptor/anchoring group has been synthesized for dye-sensitized solar cells (DSCs) with a high molar extinction coefficient of 66 700 M-1 cm(-1) at 437 nm. Theoretical calculations show that the ...

Coupled Optical and Electronic Modeling of Dye-Sensitized Solar Cells for Steady-State Parameter Extraction

Michael Graetzel, Guido Rothenberger, Matthias Schmid, Sophie Wenger

The design and development of dye-sensitized solar cells (DSCs) is currently often realized on an empirical basis. In view of assisting in this optimization process, we present the framework of a model which consists in a coupled optical and electrical mod ...

Extraordinarily efficient conduction in a redox-active ionic liquid

Michael Graetzel, Jacques-Edouard Moser, Guido Rothenberger, Shaik Mohammed Zakeeruddin, Jan Cornelius Brauer, Verner Thorsmolle

Iodine added to iodide-based ionic liquids leads to extraordi- narily efficient charge transport, vastly exceeding that expect- ed for such viscous systems. Using terahertz time-domain spectroscopy, in conjunction with dc conductivity, diffusivity and visc ...

High-efficiency (7.2%) flexible dye-sensitized solar cells with Ti-metal substrate for nanocrystalline-TiO2 photoanode

Pascal Comte, Michael Graetzel, Paul Liska, Mohammad Khaja Nazeeruddin, Guido Rothenberger, Shaik Mohammed Zakeeruddin, Péter Kalman Péchy

High-efficiency flexible dye-sensitized solar cells were fabricated with a Ti-metal foil substrate for photo anode and using a Pt-electrodeposited counter electrode on ITO/polyethylene naphthalate (ITO/PEN); these devices were characterized by incident pho ...
