The IV curve of a solar cell is the superposition of the IV curve of the solar cell diode in the dark with the light-generated current.1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode. Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes:
About Photovoltaic Energy StorageNow while testing short circuit current make sure your solar panel is not being shaded by nearby trees, shed, roofs, or any other thing. Otherwise, your short circuit current would plummet. Also before your test, don''t forget to clean your solar panel. Accumulated materials on a solar cell will mess up short circuit current output.
