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.
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:
Modules within arrays are similarly protected to form a photovoltaic generator that is designed to generate power at a certain current and a voltage which is a multiple of 12 V. Open circuit voltage Voc: When light hits a solar cell, it develops a voltage, analogous to the e.m.f. of a battery in a circuit.
The solar cell delivers a constant current for any given illumination level while the voltage is determined largely by the load resistance. The short circuit photocurrent is obtained by integrating the product of the photon flux density and QE over photon energy. It is desirable to have a high QE at wavelengths where the solar flux density is high.
Under open circuit conditions, the light-generated carriers forward bias the junction, thus increasing the diffusion current. Since the drift and diffusion current are in opposite direction, there is no net current from the solar cell at open circuit.
