How does voltage output of a solar cell increase/decrease?
It helps to understand that a solar cell is just an ordinary silicon diode (but awfully wide). It has the same curve. As it generates current, the voltage rises. As the voltage rises, the diode starts to conduct (above 0.4V), and …
Measure the open circuit voltage (Voc) across the solar cell. This is the voltage when no current is flowing through the cell. Since no current flows through a perfect voltmeter, a voltmeter measures the open circuit''s …
