Abstract

The increasing market of mobile phones, has increased the need for electricity to power mobile phones, as well. This paper investigates the possibilities to charge a mobile phone by harvesting energy from the surroundings. Some technologies are better suited for this purpose than others. Through previous analyses solar cells and electromagnetic generator were found to be the most suitable solution. This paper will give a basic description of the operating conditions of solar cells and an electromagnetic generator. There will also be a short view on the electrical circuit needed for implementing the harvested energy. Calculations regarding the power produced by amorphous silicon solar cells in both sun light and light from different light emitting sources will be examined. Furthermore calculations of the spring for the electromagnetic generator and the power produced by this device will be examined. Through experiments and data processing the energy delivered by the solar cells and the electromagnetic generator is investigated, furthermore an experiment regarding the movement of the phone will be executed.
