Hybrid systems for highly efficient and stable perovskite solar cells

Abstract : 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 has been promoted to over 20%.
