Solar cell phone chargers use solar panels to charge the cell phone batteries. They are an alternative to conventional electric cell phone chargers and in some cases can be plugged into an electrical outlet.
There are also public solar chargers for mobile phones that can be permanently installed in public places such as streets, parks and squares. The model that according to the European Commission is proclaimed as the first in the world is the Strawberry Tree, public solar charger invented by Strawberry Energy Company. This solar station won first place in "EU Sustainable Energy Week (EUSEW) 2011" in the Consume category.
Some cell phone models have a built-in solar charger [6] and are commercially available for GSM mobile phone models. Solar cell phone chargers come in different shapes and configurations, including folding (Goal Zero, Endless Sun Solar) and rotary types (Solio).
They also come in the form of straps, with solar cells on the outer surface and a nickel metal hydride battery inside. Current solar cell technology limits the effectiveness and practicality of solar chargers for everyday use. The charging times of the phone vary depending on the capacity of the installed battery that continues to increase, further extending the charging times of the solar chargers. The foldable design has been shown to allow for greater charge current while maintaining a compact size and current designs are capable of charging a modern smartphone in 3 hours. Solar chargers are also available for other cell phone accessories such as bluetooth headsets and speaker phones.
