Science of Solar
The first solid-state silicon photovoltaic cell was designed in 1954, after the development of solid-state diodes and transistors. Since then, solar popularity has been increasing and is now available in portable solar chargers. Using solar power is easy and environmentally friendly. How does it work? The solar plates are exposed to daylight. Through a clear medium, the solar power battery charger converts the suns rays into low voltage DC electricity, providing power that can be stored or used.
