The photovoltaic effect is the direct conversion of incident light into electricity by a pn (or p–i–n) semiconductor junction device. |
The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction. |
In many stand-alone PV systems, batteries are used for energy storage. Figure 4.8 shows a diagram of a typical stand-alone PV system powering DC and AC loads. |
