Perovskite solar cells can be fabricated on plastic substrates using the anti-solvent method for perovskite layer coating. We developed a semi-automated micropipette system that can control the deposition conditions of the anti-solvent method and conduct experiments. The photovoltaic conversion efficiencies were greatly affected by changing the drip timing and that by changing other drop parameters, we investigated the conditions to obtain stable and high efficiency even on plastic substrates.
