CONTENTS: INTRODUCTION DESCRIPTION CONCLUSION BIBLIOGRAPHY

How many times were we stranded because our mobile phones ran out of battery? All of us would have experienced this at least once in our life time; at least once we would have forgotten to take our mobile phone charger or that we forgot to charge our phones and it gave up at a time when we needed it very badly. Some times even when we remembered to carry our charger we may not have been able to find a power outlet that we can use to charge our mobile phones. Endless situations like these present themselves that bar us from using our mobile phones. We have got used to our mobile phones so much and without our mobile phones we feel so handicapped.

All you need to get liberated are mobile phone solar chargers. No more dead cell phones, you can always remain connected to your loved ones, you don’t have to worry about rationing you mobile phone’s energy so that you can receive important business calls. In the beginning when telephone was invented we were limited to indoor calls and now with the invention of mobile phones we got little more free because we don’t have to be glued to our office or our home to receive and make calls.

However, there was a minor glitch with the freedom that was given by mobile phones; they had to be charged to ensure that the gadget was live. To overcome this problem, outdoor charging booths erupted. They were not good enough; they did not provide a complete solution to the problem. What we have now in the form of solar travel chargers is a complete solution and complete freedom. Sunlight is one of the easiest accessible sources of energy unless you are in Norway!

No more anxiety about missing important calls or staying connected with your office. Your solar mobile phone chargers once charged fully can hold the charge even up to a year unlike the regular batteries. That drain away even without any usage. With the easiest and free source of energy you will never need a power outlet again to charge your mobile phone. You can always stay powered with solar power chargers.

Working of solar powered batteries Small photovoltaic cells or modules (groups of these cells) are displayed on a large frame and directed at the sunlight. These cells are made up of silicon semiconductors, which will absorb part of the light and convert it into energy by shaking electrons loose and allowing them to run along the semiconductor. The current then runs through the metal contacts at the top and bottom of the PV cell and can be used to power anything from a small calculator.photovoltaic cells

FIRST SOLAR PHONE  The world’s first solar phone was launched on 17 th june  This phone was developed by Hi-Tech wealth telecommunication of China.  The panels trickle-charge the battery in any amount of light, including indoors (or even by candlelight), and the battery life is 2.5 times longer than it would without the panels.
