Is solar panel monocrystalline or polycrystalline, and what are the characteristics?

　Everyone knows that solar panels are divided into monocrystalline, polycrystalline and amorphous silicon. Now most solar panels are mainly made of monocrystalline and polycrystalline. So is the solar panel better for single crystal or polycrystalline? This is indeed a problem for laymen. The editor now helps you sort out the knowledge about whether solar panels are monocrystalline or polycrystalline. Now let’s take a look at their characteristics.
1. The difference between single crystal plate material and polycrystalline plate material
Polycrystalline silicon and monocrystalline silicon are two different substances. Polycrystalline silicon is a chemical term commonly known as glass. High-purity polycrystalline silicon material is high-purity glass. Monocrystalline silicon is the raw material for solar photovoltaic cells and also the material for semiconductor chips. The raw materials of silicon ore for the production of monocrystalline silicon are scarce and the production process is complicated, so the output is low and the price is high.

Simply put, the difference between monocrystalline silicon and polycrystalline silicon lies in the arrangement of their atomic structure. Single crystals are ordered, and polycrystalline is disordered. This is mainly determined by their processing technology. Polycrystalline is mostly produced by casting. , Is to pour the silicon material directly into the pot to melt and shape, and the single crystal adopts Siemens method to improve the Czochralski, the Czochralski process is a process of reorganization of the atomic structure. To our naked eyes, the surface of monocrystalline silicon looks the same, and the surface of polycrystalline silicon looks like there are a lot of broken glass in it, which is shining.

in conclusion:

　　 Monocrystalline solar panels: no pattern, dark blue, close to black after packaging.

　　 Polycrystalline solar panels: There are patterns, polycrystalline and colorful, and polycrystalline with less color, like the snowflake crystal pattern on the snow iron sheet, light blue.

　　Amorphous solar panels: mostly glass, brown and brown
