Inkjet printing method is one of the most effective ways for fabricating large-
area perovskite solar cells. The attempt has been carried out to parameterize
the conditions of the spin-coater anti-solvent method using a micropipette. In
another experiment, inkjet printing without poor solvent with the same solution
of Cs0.05FA0.95Pb(I0.93Br0.07)3 produced a solar cell with a conversion
efficiency of 9.1% and almost no hysteresis, although the perovskite layer
thickness was less than 300 nm. Based on these results, the authors compared
the properties of crystal films deposited by the poor solvent method using a spin
coater and the inkjet method without using anti-solvents.
