Solar power generation demonstration ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
Solar cells are a response to light and can convert light energy into electricity device, solar power system in the central part of the solar panels, the solar system, the highest value. Its role is to the sun's radiation into electricity, promote the work load. The use of the experimental apparatus can understand the working principle of solar cells and solar in practical application.
Solar power generation is basically the same principle, is to describe the process of light generation crystal as an example. P-type crystalline silicon doped with phosphorus can be obtained N-type silicon to form a PN junction. When the surface of the solar cell when exposed to light, some photons absorbed by silicon material; photon energy transfer to the silicon atom, the electrons move took place more and become a free electron concentration in the PN junction formed on both sides of the potential difference, when connected to an external circuit when, under the effect of the voltage, current will flow through the external circuit produces a certain output power. The essence of this process are: photon energy is converted into electricity.
