How to make a solar cells?
Answers
Answer:- The layers of semiconductor material like Silicon having impurities are placed one over the other. When sunlight falls on these wafers, a potential difference is produced between the two regions of semiconductor's wafers. This potential difference give rise to an electric current. Thus, a device which converts sunlight into electrical energy is ready. A solar cell made of semiconductor called Germanium or silicon having gallium as impurity. It has an efficiency about 10 to 15%.
