Halide perovskites are semiconductor compounds that are highly efficient in photovoltaic solar cells for instance. These devices are promising due to the simplicity of their preparation which employs solutions and fabrication processes that are energy efficient. However, their lack of stability remains a major obstacle to their industrialization. This project aims at developing a dynamical treatment to control the crystallization and the dimensionality of the layers. The low dimensional layers are known to be more stable. Above the study of the film formation/crystallization and of the control of the structures, this project aims at preparing photovoltaic solar cells. The final devices require new competitive equipment for their PV characterizations in a reliable manner that must be bought by the laboratory.
