Force-Matching-Based Approach for the Generation of Polarizable and Nonpolarizable Force Fields Applied to CsPbI3

Ursula Röthlisberger, Ariadni Boziki, Mathias Dankl, Martin Peter Bircher

Lead halide perovskites have emerged as highly efficient solar cell materials. However, to date, the most promising members of this class are polymorphs in which a wide-band-gap delta phase competes with the photoactive perovskite alpha form and the intrin ...

From Chalcogen Bonding to S-π Interactions in Hybrid Perovskite Photovoltaics

Ursula Röthlisberger, Laura Piveteau, Virginia Carnevali, Mathias Dankl, Nikolaos Lempesis, Lorenzo Agosta, Dominik Józef Kubicki

The stability of hybrid organic-inorganic halide perovskite semiconductors remains a significant obstacle to their application in photovoltaics. To this end, the use of low-dimensional (LD) perovskites, which incorporate hydrophobic organic moieties, provi ...
