Based on the obtained waveform, the MPP point is calculated and extracted [9].The Constant Voltage algorithm [3], is based on the fact that the ratio of the array's maximum power voltage, [V.sub.mp], to its open-circuit voltage [V.sub.oc], is approximately constant.
"Open-circuit voltage is a key property that we can use to evaluate the potential of a solar cell material," Padture said.
Devices with highest dye absorbance on solid titania films show highest short-circuit current and open-circuit voltage, corresponding with 3.72% of device efficiency (Figure 2(a) and see (a) in Table 1).
FSCC and FOCV are the simplest MPPT algorithms, which are based on the linearity of short-circuit current or open-circuit voltage to the maximum power point current or voltage.
As shown in Figure 3, the self-healing characteristic-based model includes the open-circuit voltage [U.sub.OC], the internal resistance [R.sub.i] of the battery, a capacitor [C.sub.S], a resistor [R.sub.S], and a RC network.
Voltage-current density curves were obtained at a scan rate of 3 mV/s between open-circuit voltage down to 0.3 V.
The open-circuit voltage method is not a solution to partial shading conditions, but also requires a periodic isolation of the DC/DC converter from PV panel to find the [V.sub.oc] value, which means that the output power is cut off for a period of time.
These soft skin-like generators are capable of outputting an open-circuit voltage of up to 145 V and an instantaneous areal power density of 35 mW m-2.
In addition to automating I-V measurements, some SMUs feature a user-customizable interface to display the derived maximum power, short-circuit current, open-circuit voltage, or other user-derived calculations on a single screen (Figure 8) for faster and easier analysis.
Open-circuit voltage and continuous voltage (V) readings during current discharge (I) through a 10 [OMEGA] resistor (R) were recorded over the life of the batteries.
