The project is aimed at solving the fundamental problem of chemical material science - obtaining new high-efficiency perovskite-like halogenide materials (hybrid perovskites) for solar energy, which includes a scientifically based choice of stabilizing dopant structures and optimization of synthesis methods, obtaining complex thermodynamic information on the formation and disordering of matrix halides and derivatives, obtained by their doping.
The fundamental task of the project is to establish the relationship between the real - crystalline and defect - structure, the thermodynamics of formation and disordering, and the target properties (electronic and ion transport, thermal and chemical expansion, optical absorption) of hybrid perovskites, which are the basis of advanced materials for energy conversion systems. The identification of this relationship is critical to the creation of high-performance materials for practical applications.
The aim of the project is to obtain new complex information on the crystal structure and thermodynamics of formation and disordering, electrotransport and electrochemical properties, thermal and chemical expansion of hybrid perovskites such as APbX3 (A = CH3NH3, Cs, Rb; X = Cl, Br, I).
