4kw low frequency solar inverter

A solar cell is a device that responds to light and converts light energy into electricity.      

There are many kinds of materials that can produce photovoltaic effect, such as: single crystal silicon, polysilicon, amorphous silicon, gallium arsenide, indium copper selenium, and so on.                                 

The principle of their power generation is basically the same.                

Now we take crystal as an example to describe the process of photovoltaic power generation. P-type crystalline silicon can be doped with phosphorus to obtain N-type silicon and form a P-N junction.                      

When light shines on the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, which causes the electrons to migrate and become free electrons that gather on both sides of the PN junction to form a potential difference. 

When the circuit is externally connected At this time, under the action of this voltage, a current will flow through the external circuit to generate a certain output power. 

The essence of this process is: #inverter 220v 4kw        the process of converting photon energy into electrical energy.
