5 · Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
Heat batteries could store intermittent renewable energy during peak production hours, relying on a thermal version of solar cells to convert it into electricity later.
In mobile applications, like solar cars, handheld solar power meters are very useful to sense incident solar energy and fault detection (Fig. 1.6a). Indoor light levels (200–1000 lx) are very low to generate electricity compared to outdoor light levels (~10 5 lx). Nevertheless, there are devices that use solar cells indoors. In
Solar energy comes from the limitless power source that is the sun. It is a clean, inexpensive, renewable resource that can be harnessed virtually everywhere.
