Investigation of Lead-free perovskites for Optoelectronic Application

Alexander Fedorovskiy

The search for new energy sources and materials is at the foundations of scientific and technological progress. These two, often interconnected, fundamental elements open a way to create novel designs and improve existing ones for all types of machines and ...

Spatial Charge Separation as the Origin of Anomalous Stark Effect in Fluorous 2D Hybrid Perovskites

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Giulia Grancini, Valentin Ianis Emmanuel Queloz, Inés Garcia Benito, Marine Eva Fedora Bouduban, Alexander Fedorovskiy

2D hybrid perovskites (2DP) are versatile materials, whose electronic and optical properties can be tuned through the nature of the organic cations (even when those are seemingly electronically inert). Here, it is demonstrated that fluorination of the orga ...

The Role of Goldschmidt's Tolerance Factor in the Formation of A(2)BX(6) Double Halide Perovskites and its Optimal Range

Mohammad Khaja Nazeeruddin, Tom Theodorus Antonius Lummen, Nikita Drigo, Alexander Fedorovskiy

Vacancy-ordered double perovskites is a new branch of lead-free halide perovskites with properties promising for photovoltaic application. In this study, data about the crystal structure of 170 known A(2)BX(6) (X = I, Br, Cl, F) are collected and analyzed ...

Beyond Tolerance Factor: Using Deep Learning for Prediction Formability of ABX3 Perovskite Structures

Mohammad Khaja Nazeeruddin, Tom Theodorus Antonius Lummen, Valentin Ianis Emmanuel Queloz, Alexander Fedorovskiy

Deep learning (DL) is a modern powerful instrument for multiple purposes, including classification. In this study, this technique is applied to the task of perovskites formability. A commonly known perovskite dataset is used to try to make an instrument su ...
