Variation in ΔEPSC under different operating conditions: (a) Double-layer device and (b) triple-layer device under varying operating voltages (tlight = 1 s, Iop = 42 μW/cm2). EPSC generated under extreme condition (Vd = − 0.1 mV, tlight = 0.01 s, Iop = 0.17 μW/cm2) for (c) double-layer and (d) triple-layer devices.
