Voltage and current in a parallel connection of solar cells

Article no: P9511400

Principle

The pupils should examine a parallel connection of solar cells by measuring the open circuit voltage, U_ges, and the short-circuit current, I_ges.

Using a connection in parallel, greater currents can be reached.

Furthermore, the currents I₁ and I₂ at each solar cell will be measured. Using this information and I_ges, the relation relation for the parallel connection of the solar cells can be derived: I_ges = I₁ + I₂.

The voltage at each solar cell is equal to the open circuit voltage, U_ges: U_ges = U₁ = U₂.
