Task

Record the current and the voltage of a solar cell under load in dependence of the illumination level E. Determine the power P of the solar cell! What relation can be found between P and E?

Preparation

Add Equipment as shown in the diagram and set up the experiment as seen in the sketch

Execution

1. Put the lighting module on the solar cell and measure the short-circuit current and the opencircuit voltage of the solar cell!
2. Repeat the measurement with 2, 3 and 4 lamps in the lighting module! List all measurements in a table

How to use

1. click to add equipments from the Left Pane
2. click and drag dotted point endpoint to create connections

Result

Exercises

1. . Calculate the illumination level and the power of the solar cell for every number of lamps!
2. Draw the E-P-diagram!
3. What relation can be found between the power of the cell and the illumination level?
4. What is the difference between experiment 4.1 and this experiment? How can you explain this?
