Solar powered mobile phone: An innovative experiment

The charging of a mobile phone is the most important function to operate mobile. by charging the battery. Unfortunately, it will take long time for the process of full charging of a mobile phone battery and considering present generation mobile phones it is very much time taking process in to charge its battery because they are having a lot of functions need to be operated. so that The battery will be discharging quickly when mobile is working with multi functions. This process leads to be switched off the mobile. This problem is reduced with backup power banks. However, many disadvantages are present in these types of models. We can include more functions in mobile if we can able to provide power backup for long time by providing more space in the mobiles This is possible by two ways but both the ways are in opposite nature. Those are, long time power can be supply to mobile by increasing the size of battery, however this will not be a proper approach because to include more functions in mobiles the majority space in mobile will be occupied by battery. This problem can be rectified by providing alternative power to the battery continuously, hence small size battery will be sufficient to operate mobile with more features. This alternative power can be supplied by Photovoltaic (PV) cells and the possibility is to insert the PV cells on the battery. In this paper, the PV cells are used to charge the mobile battery and simulation results are presented with experimental results in various possible conditions. The proposed setup can be designed as an integrated chip, so the size of the charger will be reduced and the battery can be charged continuously from the solar power. It has been established that the performance of the proposed method is quite satisfactory during both in transient as well as in steady state is quite satisfactory under both MATLAB and experimental analysis.
