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.
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]
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:
Open-circuit voltage is then a measure of the amount of recombination in the device. 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.
Recombination at the metal-silicon interface is a major cause of the drop in the open-circuit voltage (V oc) of a solar cell. Thus far, the study of electrodes in silicon solar cells has been largely aimed at reducing the series resistance, and few studies on recombination due to electrodes have been performed.
