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.
All PV cells have both positive and negative layers — it''s the interaction between the two layers that makes the photovoltaic effect work.
