Exp-2 Recording the current-load characteristics of a solar cell as a function of the irradiance

**PHYSICS,** Class XII, Part - 2, Chapter - 14,material device & simple circuits.

V-I characteristic of a solar cell can be obtained using this apparatus. The ratio of maximum useful power and ideal power can also be calculated. The maximum useful power is the area of largest rectangle that can be formed under the V-I curve. If the voltage and current corresponding to this largest area are denoted by Vm & Im, then the maximum useful power is Vm x Im. The ratio of useful power to the ideal power is called the fill factor. It consists of solar module, decade resistance box module, lamp source, switch and circuit board.
