JV curves demonstrate the hysteresis observed from the device and include device metrics for both forward and reverse sweeps. The pixel presented (from a reverse sweep) had a power conversion efficiency of 11.8%, a Voc of 0.91 V, a FF of 79% and a Jsc of -16.5 mA/cm2. Figure 1: JV...

However, accurately measuring the efficiency and current density-voltage (JV) curves of these devices poses various challenges including the presence of mobile ions within the perovskite absorber that lead to short- and long-term transient effects. Consequently, both the measurement setup and the ...
(forward and reverse JV curves reported in Fig.S6). First, the inclusion of the 2D interfaces improved the device fill factor (FF) and VOC, ultimately enhancing its PCE. Upon polarization, i.e., keeping the device under illumination at −0.3 V before the current-voltage (J-V) scan...
000 publications in the Perovskite Database to investigate the assumed equality between the integrated external quantum efficiency and the short circuit current from JV measurements. We find a systematic discrepancy with the JV-values being on average 4% larger. This discrepancy persists across time, ...
1.1. Current-Voltage (JV) Characteristics (Voc, Jsc, FF, MPP, PCE) The collection of the JV-curve is the default characterization technique for a solar cell. Conventionally, it is obtained by performing a current−voltage (J−V) sweep under 1−sun (1000 W m−2illumination at AM1.5...
