How do solar photovoltaic (PV) panels work?

Some semiconductor silicon cells are made of photovoltaic panels. The phosphorus and boron elements are added to the silicon, which creates conductivity within the cell and allows the mobility of electrons. The electrons travel across the cell into the electrical circuit hooked up to the solar panel, when triggered by the sunlight radiation. One cell generates very little power, but when strung together in sequence, the cells work together to create considerably more power.
