The Solar IV (Current-Voltage) Curve is the characteristic curve of a solar cell, which is essential for understanding the performance of a solar cell. It is also used to determine important parameters such as the open-circuit voltage (Voc), the short-circuit current (Isc), the maximum power point voltage (Vmpp), and more.
Solar cell I-V characteristic curves that summarise the relationship between the current and voltage are generally provided by the panels manufacturer and are given as: = open-circuit voltage – This is the maximum voltage that the array provides when the terminals are not connected to any load (an open circuit condition).
Solar cell parameters gained from every I-V curve include the short circuit current, Isc, the open circuit voltage, Voc, the current Imax and voltage Vmax at the maximum power point Pmax, the fill factor (FF), and the power conversion efficiency of the cell, η [2–6].
To get the maximum power output of a solar cell it needs to operate at the maximum power point, P MP. Several important parameters which are used to characterize solar cells are discussed in the following pages.
Solar simulator I-V curve measurements of cells are typically carried out in the testing laboratory by employing a second cell, a calibrated reference cell. This reference cell is used to monitor and measure the total irradiance of the solar simu-lator during I-V testing.
