Task

Preparation

In this experiment only short-circuit currents and open-circuit voltages are measured. These cannot be measured simultaneously; in order to measure the open-circuit voltage the circuit must be broken. Set up the experiment according to the circuit diagram!

Execution

1. . Measure the current and voltage of one solar cell (see circuit diagram)!
2. . Modify the circuit so that two resp. three solar cells are connected in series. Again, measure the current and voltage!
3. Carry out analogous measurements for parallel-connected solar cells. In order to do this, develop a new circuit diagram in accordance with the diagram of the base unit.
4. Record the measured data 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

Exercises

1. Draw the I-n-diagram (n... number of solar cells) for series- and parallel-connected cells. Draw both graphs into one diagram! Use different colors for series and for parallel connection!
2. Draw the V-n-diagram for series- and parallel-connected cells. Draw both graphs into one diagram! Use different colors for series and for parallel connection!
3. Phrase a rule for the total amperage and total voltage with series- resp. parallel-connected cells!
