An equivalent circuit model of an ideal solar cell''s p–n junction uses an ideal current source (whose photogenerated current increases with light intensity) in parallel with a diode (whose current represents recombination losses). To account for resistive losses, a shunt resistance and a series resistance are added as lumped elements. The resulting output current equals the photogenerated curr…

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 …

Spectral Response

The spectral response is conceptually similar to the quantum efficiency. The quantum efficiency gives the number of electrons output by the solar cell compared to the number of photons incident on the device, while the spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell. A spectral response …

THE BEHAVIOUR OF SOLAR CELLS

The main effect of increasing temperature for silicon solar cells is a reduction in V oc, the fill factor and hence the cell output. These effects are illustrated in Fig. 3.9. Figure 3.9. The effect of temperature on the I-V characteristics of a solar cell. The temperature dependency of V oc and FF for silicon is approximated by the following ...

Silicon Solar Cell Parameters

An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick. However, thickness between 200 and 500µm are typically used, partly for practical issues such as making and handling thin wafers, and partly for …

Open-Circuit Voltage

The above equation shows that V oc depends on the saturation current of the solar cell and the light-generated current. While I sc typically has a small variation, the key effect is the saturation current, since this may vary by orders of magnitude. The saturation current, I 0 depends on recombination in the solar cell. Open-circuit voltage is then a measure of …
