Hybrid perovskites (MAPI and friends)

Our fairly prospective paper is out to review with Nano Letters at the moment, the preprint has just gone live on the arXiv. There’s a massive range of calculations presented in quite a short paper - from GSGW (MvS), periodic plane wave DFT (FB) & CCSD quantum chemical calculations (JMF) to classical electrostatic calculations (JMF). We make suggestions as the to the likely effect of these results on device operation, and route for degradation in the presence of water via the Grotthuss mechanism (CH) (and the suggestion that an aprotic cation should alleviate this).
