Working Principle

Your current location: Home>>Products>>Working Principle

The principle of the solar cell power generation mainly makes use of the photoelectric effect of semiconductor materials. P-type crystalline silicon after doped phosphorus available N type silicon, become a PN junction. When light to the surface of a solar cell, on both side of the PN junction formation of electron and hole area respectively, electronic concentrated in N area, hole on P area, some of the photons absorbed by the material; Photon energy transmitted to the silicon atoms, the electron transition occurs, become free electrons in the PN junction on both sides of the agglomeration formation potential difference, when external processing circuit, under the pressure of the voltage, there will be a current through the external circuit to produce the output power, the essence of this process is the process of the photon energy into electricity.
