Panchromatic symmetrical squaraines: a step forward in the molecular engineering of low cost blue-greenish sensitizers for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Davide Di Censo, Elisa Dell'Orto, Guido Viscardi

Two novel symmetrical blue squaraine sensitizers were synthesized, which exhibit panchromatic light harvesting and a record efficiency over 6% with J(sc) exceeding 14 mA cm(-2), and V-oc over 620 mV under 1 sun. Their color, low cost, easiness of synthesis ...

A Simple Synthetic Route to Obtain Pure Trans-Ruthenium(II) Complexes for Dye-Sensitized Solar Cell Applications

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Davide Di Censo, Filippo de Angelis, Guido Viscardi

We report a facile synthetic route to obtain functionalized quaterpyridine ligand and its trans-dithiocyanato ruthenium complex, based on a microwave-assisted procedure. The ruthenium complex has been purified using a silica chromatographic column by prote ...

Symmetric vs. asymmetric squaraines as photosensitisers in mesoscopic injection solar cells: a structure-property relationship study

Michael Graetzel, Mohammad Khaja Nazeeruddin, Davide Di Censo, Guido Viscardi

A symmetric squaraine and its related non-symmetric structure are shown to have comparable efficiencies in DSCs, but with undoubtedly advantages in the low cost and casiness of synthesis for the symmetrical structure. ...

Nanocomposites containing neutral blue emitting cyclometalated iridium(III) emitters for oxygen sensing

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Davide Di Censo, Il Jung

The behavior toward oxygen sensing of nanocomposites made of the aluminum oxide-hydroxide nanostructured solid support (AP200/19) and neutral blue emitting cyclometalated iridium(III) complexes was studied. The results are compared with the same dyes immob ...

A structural study of DPP-based sensitizers for DSC applications

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Peng Gao, Kasparas Rakstys, Davide Di Censo, Magdalena Anna Marszalek, Thomas Wesley Holcombe, Junghyun Yoon

Four D-pi-A sensitizers comprising a thienyl-diketopyrrolopyrrole (ThDPP) bridge were synthesized and tested in iodide/triiodide liquid electrolyte DSC devices. The dye series was strategically designed to develop a structure-property relationship. The bes ...
