Technical data Voltage and current of a solar cell - influence of area and illuminance with ADM3Item No. P9502100 Principle Solar cells convert solar energy into electrical energy. The maximum achievable voltage or current determines their possible applications. The maximum voltage of a solar cell is the open circuit voltage U0 at which there is no resistance in the circuit (resistance = ∞). The maximum current is the short-circuit current IK. It is reached when the resistance is zero, i.e. there is only one lead wire ("short circuit") in the circuit. In the experiment, the open-circuit voltage and short-circuit current strength are first examined as a function of the illuminated area of a solar cell. Then the solar cell is moved on the panel to change the light intensity and then these two quantities are also determined. Benefits
