The short-circuit current of a solar cell is less than the light-generated current because of the internal resistance of the cell, i.e. because of the internal leakage current. Consider the equivalent circuit of a solar cell. The internal resistance is represented by a series resistance and a shunt resistance.
The short-circuit current is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar cell is short circuited). Usually written as I SC, the short-circuit current is shown on the IV curve below. IV curve of a solar cell showing the short-circuit current.
When the solar cell is in open-circuit condition (no load), the current will be minimum and the voltage will be maximum. This voltage is known as solar cell open-circuit voltage (VOC). However, in short-circuit condition, the voltage will be minimum and the current will be maximum. This current is known as solar cell short-circuit current (ISC).
The I-V characteristics of solar cell show a negative short circuit current. Is this negative value because of minority charge carriers or not. Is it possible to explain the working of solar cell as p-n junction diode. Negative SC current signifies that the power is being generated.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.
The current produced in a solar cell is directly proportional to the intensity of radiation and is governed by the photoelectric effect, i.e., with an increase in the intensity, the current increases. However, an increase in the temperature of the solar cell reduces its voltage.
