The experimental results show that the open circuit voltage, short-circuit current, and maximum output power of solar cells increase with the increase of light intensity. Therefore, it can be known that the greater the light intensity, the better the power generation performance of the solar cell. 1. Introduction
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.
It is concluded that when the light intensity gradually increases, the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase; the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase.
Through the above research and analysis, it is concluded that the output voltage, current, and photoelectric conversion rate of solar photovoltaic cells are closely related to the light intensity and the cell temperature.
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:
