Series resistance and shunt resistance of the devices with α = 0.01∼100/ β = 1 or α = 1/ β = 0.01∼ 100. The series resistances are calculated by the inverse slope of the J – V curve at roughly 0.2 V higher in bias than in open-circuit.^{[ 29 ]} And shunt resistances are calculated by the inverse slope of the J – V curve at a reverse bias voltage of 1 V.^{[ 27 ]}
