The cited overview of Solar cell supplies background for the terminology and domain context used by this tool.^[1]

Compute the open-circuit voltage of a solar cell from its short-circuit and dark saturation current densities. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Voc (V)

Returned number in V. Open-circuit voltage.

• Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Compare the estimate with measured process data, current device documentation, and a higher-fidelity circuit, field, thermal, quantum, or TCAD model when the decision requires it.
