4.  The sun is a star made up of hydrogen and helium gas and it
radiates an enormous amount of energy every second.
 Solar cell works on the principle of photovoltaic effect. Sunlight
is composed of photons, or "packets" of energy.
 These photons contain various amounts of energy corresponding
to the different wavelengths of light.
 When a photon is absorbed, the energy of the photon is
transferred to an electron in an atom of the cell.
Itroduction

5. The basic component of a solar cell is pure silicon.

6. NEGATIVE
POSITIVE

7.  Uses high-efficiency mono crystalline silicon.
 Solar panel: 5.5V/1000mA
 Output voltage: 5.5V
 Output current: 300-550 mA
 Time taken to charge mobile phone using the
charger : about 60mintues for typical mobile.

12.  Relatively small size allows mobile use.
 System required electrical start-up power.
 Solar concentrator can be used with any heat
source.
 Higher efficiency then photovoltaic system of the
same scale.
 Ability to recharge AA batteries any time & any
where there is sun light.
 Low maintenance , emission-free &
environmentally-friendly power source.

13.  Uses low input voltage to produce high voltage
spikes of output for charging.
 Utilize renewable sources.
 Bring convenience to the users.
 Useful for users in remote area & Portable for
travelers.
 To save the electricity bill cost in the long run.
 Reduce environmental pollution.

14.  Cost is high.
 It is also applies the portable device.
 Charger is different type such as-Laptop , cell
phone & MP3 player.
 Solar charger have no capacity to store the
energy.
 They are only for use small amount of time.
 It will not work in cloudy day.
 It may not be ideal in your situation.

15.  In solar mobile charger ripples will not be there as we use DC
power directly to charge the mobile.
 Battery life is more as high voltages are not developed.
 Versatility of Solar mobile charger is high.
 Life of the battery will be high as we use solar mobile charger.
 Adaptability is high.
