Abstract

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. We have bar cast these inks to produce
photoactive perovskite thin films which are significantly more
stable to humidity than solution-processed films. This new method
also avoids the use of toxic DMF solvent.
