Fig. 4: Change of carrier concentrations and their mapping using A-SCLC model.

Voltage dependence of free (pf) and trapped (pt) charge carriers for a MAPbBr3 and b MAPbI3 and energy dependances of pf and pt for c MAPbBr3 and d MAPbI3. The solid blue and red lines represent model curves (ntm and ptm) of trapped charge carriers. Red dashed line represents model curve of free charge carriers (pfm).
