Many different solar cell technologies are being developed, for various applications (rooftops, solar power plants, satellites, backpacks or clothing, etc.). The authors are studying a diagnostic method of a PV power generating system. Battery storage either on or off-grid is more complicated. 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. It is shown in the v-i characteristics of solar cell by P m. Working of a Solar Cell. A commonly used parameter that characterizes a solar cell is the fill factor, FF, which is defined as the ratio of P MAX to the area of the rectangle formed by V OC and I SC.
