Protocol

Here, we present a protocol to adjust the properties of solution-processed CH3NH3PbI3 through the incorporation of monovalent cation additives in order to achieve highly efficient perovskite solar cells.

Difficulty
advanced
Total time
~4–6 hours per batch of samples (including drying/annealing steps)

Steps

1
Prepare and clean FTO-coated glass substrates

Clean fluorine-doped tin oxide (FTO)-coated glass slides using standard procedures to remove contaminants and prepare the surface for subsequent layer deposition.
