A fast and robust numerical scheme for solving models of charge carrier transport and ion vacancy motion in perovskite solar cells [PDF]

, 2018
Drift-diffusion models that account for the motion of both electronic and ionic charges are important tools for explaining the hysteretic behaviour and guiding the development of metal halide perovskite solar cells. Furnishing numerical solutions to such

A novel dimethylformamide (DMF) free bar-cast method to deposit organolead perovskite thin films with improved stability [PDF]

, 2016
We report a solvent-free approach to synthesizing organolead perovskites by using solid state reactions to coat perovskite crystals onto Al2O3 or TiO2 nanoparticles followed by addition of terpineol affording perovskite inks.
