TL;DR: In this paper, it was demonstrated that significant decomposition effects already occur during annealing of a methylammonium lead triiode perovskite at 85 °C even in inert atmosphere, thus violating international standards.

TL;DR: One-year stable perovskite devices are shown by engineering an ultra-stable 2D/3D (HOOC(CH2)4NH3)2PbI4/CH3NH3Pb mezzanine junction, which will enable the timely commercialization of perovSKite solar cells.

TL;DR: In this paper, first-principles computational analyses were carried out on the tetragonal MAPbI3 (MA = methylammonium) perovskite and on its interface with TiO2, and it was shown that negatively charged defects, close to the electron transport layer (TiO2 in our case) modify the perovsite electronic state landscape, hampering charge extraction at selective contacts, thus contributing to the observed solar cell hysteresis.

TL;DR: An effective GW method incorporating spin-orbit coupling is developed which allows us to accurately model the electronic, optical and transport properties of CH3NH3SnI3 and CH3 NH3PbI3, opening the way to new materials design.

TL;DR: A fully first-principles investigation on APbI3 perovskites with A = Cs(+), MA, and FA shows evidence that the tetragonal-to-quasi cubic structural evolution observed when moving from MA to FA is due to the interplay of size effects and enhanced hydrogen bonding between the FA cations and the inorganic matrix altering the covalent/ionic character of Pb-I bonds.
