Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

thesis

Systèmes hybrides pour cellules solaires à pérovskite stables à haut rendement ; Hybrid systems for highly efficient and stable perovskite solar cells

  • Geffroy, Camille
Abstract

Les cellules solaires comprenant comme matériau actif une pérovskite organométallique hydride sont apparues récemment comme une technologie de haute performance et bon marché pour la conversion de l’énergie solaire. Les efforts mobilisés pendant cette thèse se sont concentrés sur un composant clé des cellules solaires à pérovskite, le transporteur de trous, qui assure à la fois les performances et la stabilité des cellules. Les avantages des polymères semi-conducteurs pour cette fonction se retrouvent dans leur stabilité, leurs bonnes propriétés de transport de charge et leur caractère filmogène. Ainsi, la stabilité des cellules solaires à pérovskite planes a pu être améliorée en intégrant un polyvinylcarbazole fonctionnalisé, tout en conservant de bonnes efficacités. Le potentiel de polyélectrolytes à base de PEDOT a pu être évalué dans les cellules de type inverses. Et enfin, une nouvelle méthode de dopage par un polyélectrolyte à base d’imidazole a démontré des efficacités remarquables, supérieures à 20%. ; Perovskite solar cells based on hybrid organometal perovskite recently appeared as a cost-effective and highly efficient technology for the conversion of sunlight. Efforts undertaken during this PhD thesis focused on one component of the perovskite solar cells, the hole transport material, which rules both, performance and stability of the devices. Advantages of semiconducting polymers result in their thermal and chemical stability, their good charge transport properties and their ability to form homogeneous thin films. Thereby, through synthesis of novel polyvinylcarbazole and incorporation into devices, stability of planar perovskite solar cells has been enhanced while conserving good efficiency. The potential of PEDOT-based polyelectrolytes has been investigated in inverted perovskite solar cells. Finally, a new strategy to efficiently dope hole transporting materials has been demonstrated through the introduction of N-heterocyclic imidazolium-based polyelectrolytes. Thereby, efficiency of solar cells ...
