Efficient Electron Transfer and Sensitizer Regeneration in Stable π-Extended Tetrathiafulvalene-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Robin Humphry-Baker, Joël Teuscher, Davide Di Censo, Sophie Wenger, Qianli Chen

The development of metal-free organic sensitizers is a key issue in dye-sensitized solar cell research. We report successful photovoltaic conversion with a new class of stable tetrathiafulvalene derivatives, showing surprising electrochemical and kinetic p ...

An inconvenient influence of iridium(III) isomer on OLED efficiency

Michael Graetzel, Mohammad Khaja Nazeeruddin, Davide Di Censo, Filippo de Angelis

The recently reported heteroleptic cyclometallated iridium(III) complex [Ir(2-phenylpyridine)(2)(2-carboxy-4-dimethylaminopyridine)] N984 and its isomer N984b have been studied more in detail. While photo- and electrochemical properties are very similar, D ...

Molecular design of metal-free D–π-A substituted sensitizers for dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Robin Humphry-Baker, Joël Teuscher, Davide Di Censo, Nuttapol Pootrakulchote, Yuxiang Yu, Leila Alibabaei

Novel donor-p-acceptor (D--A) dyes, coded as SD-1, SD-2 and SD-5, were designed and synthesized for dye-sensitized solar cells. All these dyes comprised the same donor and acceptor units while the oligo thiophene units were introduced as linkers between th ...

Application of Cu(II) and Zn(II) coproporphyrins as sensitizers for thin film dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Pascal Comte, Joël Teuscher, Davide Di Censo, Leila Alibabaei

We synthesized the Cu(II) and Zn(II) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21H,23H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper(II) coproporphyrin-I exhib ...

New electrolytes for high power Li-ion batteries : electrochemical stability, Li-ion insertion kinetics and corrosion inhibition properties

Davide Di Censo

A new generation of high power Li-ion batteries that avoid carbon as anodic material replacing it with the spinel Li4Ti5O12 has been studied in this work. For these new Li-ion cells new electrolyte compositions can be considered. The main work of this thes ...
