Solar Cell Properties and Design
Next, the equivalent circuit of solar photovoltaic cells is described, followed by the explanation of the I-V curve and the P-V curve. These curves introduce the concepts of open-circuit voltage, short-circuit current, and maximum power point of the solar photovoltaic cell in this chapter, which will be necessary throughout the rest of the book.
The photovoltaic effect
The current from the solar cell is the difference between I L and the forward bias current. Under open circuit conditions, the forward bias of the junction increases to a point where the light-generated current is exactly balanced by the forward bias diffusion current, and the net current is zero. ... Since the drift and diffusion current are ...

J sc - Short-circuit current density; V oc - Open-circuit voltage; The PCE can be calculated using the following equation: Here, P out (P in) is the output (input) power of the cell, FF is the fill factor, and J sc and V oc are the short-circuit current density and open-circuit voltage respectively.
Open Circuit Voltage
Open circuit voltage is a common term in solar cell applications. V OC is the open circuit voltage, which is the maximum voltage that is available for drawing out from a solar cell, and occurs at zero current. The open circuit voltage resembles the forward bias amount on the solar cell as a result of the bias of the solar cell junction with ...
