The Theory and Simulation of Condensed Matter (TSCM) group in the Physics Department of King's College London invites applications for a postdoctoral position in theory and simulation of the electronic structure of the new class of hybrid halide perovskite solar cells using advanced electronic structure techniques (particularly the quasiparticle self-consistent GW approximation). These devices have recently attracted strong interest in the Photovoltaics community: they they show high efficiency; and they are synthesised with low-technology fabrication processes out of abundant materials.  Theory predicts that they have unusual ferroelectric and spin-orbit properties, which may be connected with the good performance observed.
