Solar panels can produce power because the the sunlight illuminates on the panels, it actually illuminates on the PN junction. It will form new hole electron pair. Under the action of PN junction field, the holes move to area p from area n, the electrics move to area n from area p. Close the circuit, an electric current is formed on it.
Nowadays,solar energy as a kind of new energy is being developed all over the world,because it will never pollute the environment.Although a solar power station will cost lots of money to be built, it is still necessary in the case of that we have only one earth.
This is our model of PV.It directly shows how the solar panel works.If the switch is pressed under the sunlight,the little bulb on the wooden house will shine slightly.The model is almost formed by used materials,it shows the eco-friendly theme of this model.
