How does a solar panel make electricity?
“. How Does a Solar Panel Make Electricity Solar cells make use of the photoelectric effect for the production of electricity. Pure crystalline silicon is a not a good conductor of electricity. Its electrons are not free to move about and carry an electrical charge. So atoms of other elements are added to 99.999 % pure silicon. Atoms of elements such as boron, added to silicon, results in a p-type silicon, which readily accepts electrons. Atoms of phosphorus added to silicon creates n-type silicon, which readily supplies electrons. Solar cells, which are also known as photovoltaic cells, are made using a p-type silicon layer, n-type silicon layer and a transparent electrically conductive layer. It also has metal contact layer and a p-n junction. When sunlight falls on both the silicon layers of the solar cell, electrons and positive charges (protons) get excited and start moving within the layers. This flow of electrons is known as electrical current. These moving charges are then chan
