Effect of FABr Over-Stoichiometry on the Morphology and Optoelectronic Properties of Wide-Bandgap FAPbBr_3 Films
G. Ammirati, F. Martelli, F. Toschi +9
In this study, we investigate the impact of formamidinium bromide (FABr) over-stoichiometry in the precursor solution on the optoelectronic properties and morphology of the resulti…
Electron-Hole Separation Dynamics and Optoelectronic Properties of a PCE10:FOIC Blend
G. Ammirati, S. Turchini, F. Toschi +11
Understanding charge separation dynamics in organic semiconductor blends is crucial for optimizing the performance of organic photovoltaic solar cells. In this study, we explored t…
The speed of sound and elastic properties of single crystals of inorganic and hybrid lead-free iodide perovskites obtained by femtosecond transient optical reflectivity
Giuseppe Ammirati, Patrick O Keeffe, Stefano Turchini +8
Optoelectronic devices operate under continuous thermal stress that may influence both long-term stability and optical properties of the active material. It is therefore useful to…
Hole Transfer Dynamics in Thin Films of Mixed-Dimensional Quasi-2D Perovskites
G. Ammirati, S. Turchini, F. Toschi +8
The understanding of charge transfer processes in mixed-dimensional quasi-2D perovskites is crucial for their application in high-performance photovoltaic devices. In this work, we…
Gold diamond Nanocomposites Efficiently Generate Hydrated Electrons upon Absorption of Visible Light
Silvia Orlanducci, Giuseppe Ammirati, Alessandro Bellucci +8
An efficient source of hydrated electrons generated by visible light has the potential to have a major impact on solar homogeneous catalysis. Diamond has potentially a high capabil…
