A solar cell is a semiconductor PN junction diode, normally without an external bias, that provides electrical power to a load when illuminated (Figure 1). 2. Solar cell. As an introduction, therefore, Chapter 1 is devoted to a brief characterization of sunlight and basic electric parameters of solar cells. Because the output terminals are shorted, the output voltage is 0 V. For an open output, the voltage, VOCis maximum (0.6 V) in this case, but the current is 0 A, as indicated. Solar Cell IV Curves. The equation for the IV curve in the first quadrant is: Ideal Solar Cell. Solar Cell I-V Characteristic Curves are graphs of output voltage versus current for different levels of insolation and temperature and can tell you a lot about a PV (Photovoltaic-which converts light energy into electricity) cell or panel’s ability to convert sunlight into electricity.
