The measurement of the real defect concentration by Photo-induced current transient spectroscopy method (PICTS) is still unattainable owing to the presence of reflecting metal layer contacts that avoid the knowledge of the real absorbed photons number and then the real photogenerated current in the sample. The combination of the two methods PICTS and space charge limited current (SCLC) allows to the extraction of the mean apparent absorption coefficient of the excitation light in the considered sample, as a consequence that leads to solve few main problems like: the scaling of PICTS spectra in term of real defect concentration and the μτ product evolution.
