This document discusses the design and specifications of a solar mobile phone charger. It begins with an introduction to solar cells and the photovoltaic process. It then provides details on the components used, including a high-efficiency mono-crystalline silicon solar panel rated at 5.5V/1000mA. The block diagram and circuit diagram are presented. Applications and advantages include portable power generation with no emissions. Disadvantages include high initial cost and inability to store power. The conclusion notes benefits such as increased battery life and lack of ripples when using direct DC charging from the solar panel.

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

ï‚¢ Relatively small size allows mobile use. ï‚¢ System required electrical start-up power. ï‚¢ Solar concentrator can be used with any heat source. ï‚¢ Higher efficiency then photovoltaic system of the same scale. ï‚¢ Ability to recharge AA batteries any time & any where there is sun light. ï‚¢ Low maintenance , emission-free & environmentally-friendly power source.
ï‚¢ Uses low input voltage to produce high voltage spikes of output for charging. ï‚¢ Utilize renewable sources. ï‚¢ Bring convenience to the users. ï‚¢ Useful for users in remote area & Portable for travelers. ï‚¢ To save the electricity bill cost in the long run. ï‚¢ Reduce environmental pollution.
ï‚¢ Cost is high. ï‚¢ It is also applies the portable device. ï‚¢ Charger is different type such as-Laptop , cell phone & MP3 player. ï‚¢ Solar charger have no capacity to store the energy. ï‚¢ They are only for use small amount of time. ï‚¢ It will not work in cloudy day. ï‚¢ It may not be ideal in your situation.
ï‚¢ In solar mobile charger ripples will not be there as we use DC power directly to charge the mobile. ï‚¢ Battery life is more as high voltages are not developed. ï‚¢ Versatility of Solar mobile charger is high. ï‚¢ Life of the battery will be high as we use solar mobile charger. ï‚¢ Adaptability is high.
