How a photovoltaic module is formed?
A photovoltaic module is formed by the connection of multiple solar cells connected in series and/or in parallel to obtain the desired voltage and current. A solar cell is a semiconductor system that absorbs light (solar energy) and converts it directly into electrical energy.
Can a solar cell be modeled as a current source?
The ideal solar cell theoretically can be modeled as a current source with an anti-parallel diode (see Fig. 1).
