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...
N+P photodetector characterization using the quasi-steady state photoconductance decay method 光电导衰减法光电探测器NP准稳态特性表面复合少数载流子速度检测器When a material is irradiated,it becomes more electrically conductive due to the absorption of the electromagnetic radiation.As a result,the number ...
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 ...

A simple but interesting phenomenon to characterise a fabricated n+p photodetector in order to determine its linearity (photoresponse) and photoconductance was employed. Using the transient decay when the irradiation source is switched off, the minority carrier concentration, effective lifetime and ...
