We apply the contactless quasi-steady-state photoconductance (QSSPC) method to co-evaporated methyl ammonium lead iodide (MAPbI3) perovskite thin-films. Using an adapted calibration for ultralow photoconductances, we extract the injection-dependent carrier lifetime of the MAPbI3layer. The life...

Quasi-steady state photoconductance (QssPc) measurements were used to monitor the lifetime of different mc-Si substrates and process sequences. It is important to identify the beneficial or detrimental processing steps, to minimise recombination (and therefore efficiency) at the completion of ...
