In the coating of perovskite layers for perovskite solar cells, a process that does
not use anti-solvents is extremely important from the viewpoints of safety in the
working environment. For these reasons, the ink-jet method has been studied
as a process that enables the coating of perovskite layers without using anti-
solvents. The anti-solvent free method gave an energy conversion efficiency of
9.86% in a solar cell with a perovskite layer thickness less than 300 nm and
with high roughness. Further studies were conducted to increase the flatness
and thickness of the perovskite layer.
