How to use the photovoltaic cell thickness gauge
A solar cell can produce up to 2 W of energy. When load current is zero, its voltage becomes maximum and is known as open-circuit voltage V oc.When load current increases, short circuit current I sc is reached, and voltage becomes zero. Power from a solar cell shows a bell-type behavior between these two extremes of zero power. - Download [PDF]
