It is convenient to express the electrical circuitry of a solar cell as an equivalent diagram.
The IV curve of a solar cell is the superposition of the IV curve in the dark with the light-generated current. Illumination shifts the IV curve down into the fourth quadrant where power can be extracted from the diode. Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes:
An equivalent circuit model presents a theoretical circuit diagram, which captures the electrical characteristics of a device. It is important to note the components illustrated in the model are not physically present in the devices themselves.
When comparing solar cells of the same material type, the most critical material parameter is the diffusion length and surface passivation. In a cell with perfectly passivated surface and uniform generation, the equation for the short-circuit current can be approximated as: n p are the e-and h+diffusion lengths respectively.
For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum; the collection probability of the solar cell, which depends chiefly on the surface passivation and the minority carrier lifetime in the base.
