Tasks:

– synthesis, deposition and chemistry optimization of the component layers in PSCs structures; that is including different electron transporter materials (TiO₂ and SnO₂) and compositional engineering of the halide perovskite material.

– advanced chemical, structural and optical analyses (XRD, SEM, Raman, AFM, FTIR)

– development of the printing technnology and of the chemical methods to prepare the precursor materials; solvent engineering needed for passing from small area spin-coating technique to the deposition of the perovskite layer using large area techniques (slot-die) were the use of anti-solvents is not possible anymore. Two different printing methods are used, the spray deposition for the ETL oxide films and slot die for depositing the perovskite and organic layers in PSC structures

– fabrication of small and large area standard and inverted PSCs

– electrical and photovoltaic characterization of small and large areas PSCs, a necessary step to provide experimental quantities necessary as inputs for theoretical modelling (J-V characteristics, EQE, PCE, impedance spectroscopy)- in addition to the role envisaged in the project, PP addressed also the deposition of Cu and Ni oxides by sputtering

Tasks:

• DFT calculations to describe the band alignment at the new perovskite/ETM interface (e.g. SnO₂ as ETM) and a characterization of the TiO₂/SnO₂ interface
• DFT calculations to describe the band alignment at the interface between the perovskite and the inorganic HTM (e.g. Cu₂O, other transition metal oxides). 
• Modelling iodine migration in the HP layer using molecular dynamics. Force field parametrizations from DFT calculations used as input for molecular dynamics codes (LAMMPS).
