“…However, a sharp decline in the device parameter is observed as the concentration of SQD increases to 0.625 wt % SQD, which showed a decrease in PCE to 4.89% (see Table ). The drop in the cell parameters can be linked to the reduced values of current density and increase in the series resistances, which suggests that the high concentration of SQD in the electron selective layer impedes the good morphology of the device and promotes charge recombination at the interfaces. , Table shows a summary of the devices’ parameters with ranges of values for the different diodes.…”

“…The drop in the cell parameters can be linked to the reduced values of current density and increase in the series resistances, which suggests that the high concentration of SQD in the electron selective layer impedes the good morphology of the device and promotes charge recombination at the interfaces. 32,64 Table 2 shows a summary of the devices' parameters with ranges of values for the different diodes. The notable surge in the measured current densities for devices (0.125 and 0.375 wt %) with modified ETL can be linked to the alteration of energy levels consequently reducing the energy losses as provided in Figure 3c and Table 2.…”
