Research paper thumbnail of Carbazol-N-yl and diphenylamino end-capped triphenylamine-based molecular glasses: synthesis, thermal, and optical properties

Tetrahedron Letters, 2013

The molecules exhibit high glass-transition temperatures (74-151°C), excellent thermal stability, and are soluble in common organic solvents. Moreover, most of them absorb mainly in UV domain. These star-shaped triphenylamine derivatives are promising hole transporting materials for solid-state dye-sensitized solar cell applications.

Research paper thumbnail of Matériaux de transport de trous à base de petites molécules organiques pour cellules photovoltaïques hybrides solides

Matériaux & Techniques, 2013

Issues de la technologie propre aux couches minces, les cellules solaires hybrides sensibilisées ... more Issues de la technologie propre aux couches minces, les cellules solaires hybrides sensibilisées par un colorant comptent parmi les plus prometteuses dans le domaine desénergies renouvelables. Elles doivent leur succès non seulementà leur légèreté,à la possibilité de réaliser de grandes surfaces souples, mais aussì a leur rendement photovoltaïque de plus en plus appréciable (12 % avec unélectrolyte liquide ; 7 % pour une cellule tout solideà base de verre moléculaire). Cet article met enévidence les progrès récents sur l'utilisation de verres moléculaires comme matériaux de transport de trous pour réaliser des cellules tout solide. En effet, ces derniers doivent posséder des propriétés physiques et chimiques particulières répondant a la fois au fonctionnement d'une cellule photovoltaïque età sa mise en oeuvre. Par unétat de l'art, nous citerons et analyserons les caractéristiques de ces nouveaux matériaux.

Research paper thumbnail of Recent advances in small molecular, non-polymeric organic hole transporting materials for solid-state DSSC

Their success is not only due to their low weight, the possibility of making large flexible surfaces, but also to their photovoltaic efficiency which are found to be more and more significant (>12% with a liquid electrolyte, >7% with a solid organic hole conductor). This short review highlights recent advances in the characteristics and use of low-molecular-weight glassforming organic materials as hole transporters in all solid-state dye-sensitized solar cells. These materials must feature specific physical and chemical properties that will ensure both the operation of a photovoltaic cell and the easy implementation. This review is an english extended version based on our recent article published in
