Typically, the I-V characteristics curve is drawn at one sun radiation (1000 W/m 2) however, variation in solar radiation value predominantly changes the current output from the solar panel and subsequently the power output. The output voltage from solar panel is highly dependent on the operating temperature of the solar cells.
Then the span of the solar cell I-V characteristics curve ranges from the short circuit current ( ) at zero output volts, to zero current at the full open circuit voltage ( ). In other words, the maximum voltage available from a cell is at open circuit, and the maximum current at closed circuit.
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.
The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.
The main electrical characteristics of a PV cell or module are summarized in the relationship between the current and voltage produced on a typical solar cell I-V characteristics curve.
To measure the current-voltage characteristics of a solar cell at different light intensities, the distance between the light source and the solar cell is varied. Moreover, the dependence of no-load voltage on temperature is determined.
