6 FAQs about [Open circuit voltage of silicon solar cells]

What is open-circuit voltage in a solar cell?

The open-circuit voltage, V OC, is the maximum voltage available from a solar cell, and this occurs at zero current. The open-circuit voltage corresponds to the amount of forward bias on the solar cell due to the bias of the solar cell junction with the light-generated current. The open-circuit voltage is shown on the IV curve below.

How do you determine the voltage of a silicon solar cell?

Silicon solar cells on high quality single crystalline material have open-circuit voltages of up to 764 mV under one sun and AM1.5 conditions 1, while commercial silicon devices typically have open-circuit voltages around 690 mV. The V OC can also be determined from the carrier concentration 2: V O C = k T q ln [(N A + Δ n) Δ n n i 2]

How do you find open-circuit voltage in a solar cell?

The open-circuit voltage is shown on the IV curve below. IV curve of a solar cell showing the open-circuit voltage. An equation for V oc is found by setting the net current equal to zero in the solar cell equation to give:
