Résumé

Unique donor-π-acceptor phthalocyanines have been synthesized through the asym. functionalization of an ABAB phthalocyanine, crosswise functionalized with two iodine atoms through Pd-catalyzed cross-coupling reactions with adequate electron-donor and electron-acceptor moieties. These push-pull mols. have been optically and electrochem. characterized, and their ability to perform as chromophores for dye-sensitized solar cells has been tested.

Cellule solaire à pigment photosensible

Une cellule solaire à pigment photosensible parfois appelée cellules Grätzel (en anglais, Dye-sensitized solar cell ou DSC) est un système photoélectrochimique inspiré de la photosynthèse végétale qui, exposé à la lumière (photons), produit de l’électricité. Elle est souvent désignée par l'acronyme dérivé de son appellation en anglais : dye-sensitized solar cell, DSC, DSSc voire DYSC). Les cellules Grätzel ont été nommées ainsi en référence à son concepteur, Michael Grätzel, de l’École polytechnique fédérale de Lausanne.

Film photovoltaïque

Un film photovoltaïque ou cellule solaire en couche mince ou encore couche mince photovoltaïque est une technologie de cellules photovoltaïques de deuxième génération, consistant à l'incorporation d'une ou plusieurs couches minces (ou TF pour ) de matériau photovoltaïque sur un substrat, tel que du verre, du plastique ou du métal. Les couches minces photovoltaïques commercialisées actuellement utilisent plusieurs matières, notamment le tellurure de cadmium (de formule CdTe), le diséléniure de cuivre-indium-gallium (CIGS) et le silicium amorphe (a-Si, TF-Si).

Hybrid solar cell

Hybrid solar cells combine advantages of both organic and inorganic semiconductors. Hybrid photovoltaics have organic materials that consist of conjugated polymers that absorb light as the donor and transport holes. Inorganic materials in hybrid cells are used as the acceptor and electron transporter in the structure. The hybrid photovoltaic devices have a potential for not only low-cost by roll-to-roll processing but also for scalable solar power conversion. Solar cells are devices that convert sunlight into electricity by the photovoltaic effect.
