Multi-Objective Quality-Diversity for Crystal Structure Prediction

1 code implementation25 Mar 2024 Hannah Janmohamed, Marta Wolinska, Shikha Surana, Thomas Pierrot, Aron Walsh, Antoine Cully

This approach overlooks other potentially interesting materials that lie in neighbouring local minima and have different material properties such as conductivity or resistance to deformation.

Illuminating the property space in crystal structure prediction using Quality-Diversity algorithms

no code implementations6 Mar 2024 Marta Wolinska, Aron Walsh, Antoine Cully

Consequently, we also show the value of using neural networks to model crystal properties and enable the identification of novel composition--structure combinations.

Probing the ionic defect landscape in halide perovskite solar cells

no code implementations14 May 2020 Sebastian Reichert, Qingzhi An, Young-Won Woo, Aron Walsh, Yana Vaynzof, Carsten Deibel

Metal halide perovskites are a remarkable class of materials with particular promise for application in optoelectronics.

Thermodynamic stabilization of mixed-halide perovskites against phase segregation

no code implementations15 Jan 2020 Eline M. Hutter, Loreta A. Muscarella, Francesca Wittmann, Jan Versluis, Lucie McGovern, Huib J. Bakker, Young-Won Woo, Young-Kwang Jung, Aron Walsh, Bruno Ehrler

Mixing iodide and bromide in halide perovskite semiconductors is an effective strategy to tune their bandgap, therefore mixed-halide perovskites hold great promise for color-tunable LEDs and tandem solar cells.

Impact of non-parabolic electronic band structure on the optical and transport properties of photovoltaic materials

1 code implementation6 Nov 2018 Lucy D. Whalley, Jarvist M. Frost, Benjamin J. Morgan, Aron Walsh

For semiconductors used in photovoltaic devices, the effective mass approximation allows calculation of important material properties from first-principles calculations, including optical properties (e. g. exciton binding energies), defect properties (e. g. donor and acceptor levels) and transport properties (e. g. carrier mobilities).
