The short-circuit current from a solar cell depends linearly on light intensity, such that a device operating under 10 suns would have 10 times the short-circuit current as the same device
A solar cell generates a current by collecting photons over its surface area. But solar cells come in many different sizes, so to allow them to be compared with each other the current is normalised by the area. The open circuit voltage is not dependent on the area, but the other properties of the diode. It does have a dependence on illumination
Negative SC current signifies that the power is being generated. If both the current and voltage are positive, it means that the power P=I*V is being consumed. You can see the VI characteristic of...

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.
Typical representation of an I-V curve, showing short-circuit current (I sc and open-circuit voltage (V oc) points, as well as the maximum power point (V mp, I mp). The two limiting parameters used to characterise the output of solar cells for given irradiance, operating temperature and area are (Shockley & Queisser, 1961): 1. Short circuit
However, it is also possible for modules to be wired into a state of short-circuit, which is more of a concern both in terms of long-term module reliability and for site safety. This article discusses the defect mode of short

Short circuit current is the current that flows through a solar cell when it is connected directly to a load with no external resistance. The short circuit current is determined by the material and design of the solar cell, and is a function of the light intensity incident on the cell.

The short-circuit current from a solar cell depends linearly on light intensity, such that a device operating under 10 suns would have 10 times the short-circuit current as the same device under one sun operation. However, this effect does not provide an efficiency increase, since the incident power also increases linearly with concentration

In this work, some of the solar cell physics basic concepts that establish limits for the efficiency, the short-circuit current density, the open-circuit voltage and even the fill factor for solar cells are reviewed. All these parameter limits will be shown as a function of the active semiconductor bandgap for single junction cells under the
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 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 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.
As losses due to short-circuit current depend on the square of the current, power loss due to series resistance increases as the square of the concentration. Solar cells experience daily variations in light intensity, with the incident power from the sun varying between 0 and 1 kW/m 2.
In the case of very high series resistance (> 10 Ωcm 2) I sc is less than I L and writing the solar cell equation with I sc is incorrect. Another assumption is that the illumination current I L is solely dependent on the incoming light and is independent of voltage across the cell.
Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.
