In this paper the researchers report on a oligomer treatment of MAPI films which efficiently passivate defects by coordination with Pb ions. With additional improvements in crystallization and charge transport properties, the resulting cell had a PCE of 21.23% and showed better stability.

Paios was used to determine shorter TPC decay time and longer TPV lifetime was used to confirm the improved charge extraction properties.
