The effect of solar cell capacitance in the electrical characterization of photovoltaic (PV) modules at Standard Test Conditions (STC) is known since the 1990s.
The capacitor represents the accumulation of charges in the PV device. The capacitance of a PV device is attributed to both junction capacitance and diffusion capacitance, both of which are voltage dependent.
This way both the front and middle electrodes were contacted for testing the solar cell before it was joined with the supercapacitor. MPNCs were synthesized via the oxidative polymerization of aniline in the presence of silica NPs as the hard template, adapted from the procedure reported by us previously.
The electrical behaviour of a solar cell can be described in classical physics terms with the equivalent circuit of figure 1, which represents the single diode capacitive model of a solar cell.
Newer solar simulators allow the operator to manually 'shape' the profile of the voltage ramp: in the shaped sweep I–V (figure 12 ), then, d V /d t can be 'built' [ 27] to be as slow as needed at voltages close to the maximum power point, and thus mitigate the capacitive effect.
The surface photovoltage technique is incapable of measuring structures with non-transparent contacts, while the capacitance-voltage technique shows saturation at high built-in voltages due to the formation of an inversion layer.
