PhotovoltaicSolar Cells<\/a>The function of the film, as the name suggests, is that its main function is to convert energy into electricity through the photovoltaic effect.<\/p>\n

There are many kinds of materials that can be used in solar cells and produce photovoltaic effect, such as: single crystal silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper indium selenide, etc.<\/p>\n

Although there are many kinds of materials that can produce photovoltaic effect, their power generation principles are basically the same. Now let's take crystal as an example to introduce the process of photovoltaic power generation. P-type crystalline silicon can be doped with phosphorus to obtain N-type silicon, forming a PN junction. When light shines on the surface of the solar cell, some photons are absorbed by the silicon material, and the energy of the photons is transferred to the silicon atoms, causing the electrons to migrate and become free electrons, which gather on both sides of the PN junction to form a potential difference. When the circuit is connected to the outside world, under the action of voltage, current flows through the external circuit to generate a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.<\/p>\n
