Dans le cadre de la transition énergétique, les pérovskites hybrides organiques-inorganiques apparaissent comme des absorbeurs de choix pour des cellules solaires à haut rendement et faible coût. Ce livre explore l’élaboration et la caractérisation de nouveaux alliages de type ABX₃ et d’hétérojonctions pérovskite / ZnO ou TiO₂. Les pérovskites hybrides ont rapidement émergé comme des semi-conducteurs pour les applications solaires grâce à la combinaison inédite de quatre propriétés clés : un haut coefficient d’absorption optique, une longueur de diffusion des porteurs, une énergie de défauts profonds élevée qui tolère des désordres structuraux sans piégeage massif, et la possibilité d’ajuster le gap. Ces caractéristiques permettent la fabrication de cellules solaires en couche mince, réduisant ainsi l’empreinte énergétique et le coût par rapport aux technologies silicium. Ce travail établit des protocoles reproductibles de synthèse à l’air, qui identifie les fenêtres de température et de composition garantissant une stabilité structurale et optique, et valide des architectures pérovskite/oxyde directement transférables vers des empilements de cellules solaires.
