Charge carrier behavior in perovskite thin films is crucial to their optoelectronic performance; yet, the impact of antisolvents and self-assembled monolayers (SAMs) on their basic charge carrier transport properties remains not fully understood. In this work, FAPbI3 and FAMACsPbBr3 perovskite systems are investigated to gain a more comprehensive understanding of how processing additives influence charge generation, transport, and recombination. The mobility and lifetime of photogenerated charge carriers in perovskite layers are determined in a non-contact way using Time-Resolved Microwave conductivity (TRMC), where the interaction of an applied electro-magnetic field with the charge carriers results in a time-dependent change in conductance. Complementary time-resolved photoluminescence (trPL) measurements support the interpretation of TRMC-derived carrier dynamics. Together, TRMC and trPL provide insight into how processing additives influence charge-carrier dynamics in perovskite materials.
