A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. 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). This apparatus allows students in introductory physics course to plot I-V characteristics of a solar cell by a simple experiment. 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. 0000001022 00000 n
