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.

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.
