Which is better solar panel, monocrystalline or polycrystalline?

Introduction Which is better solar panel, monocrystalline or polycrystalline? Solar panels absorb sunlight and convert the energy from solar radiation through the photoelectric effect or actination.

Which is better solar panel, monocrystalline or polycrystalline?

Solar panel is a device that absorbs sunlight and converts solar radiation energy directly or indirectly into electrical energy by photoelectric effect or photochemical effect. The main material of most solar panels is "silicon", but due to its high cost. production, it cannot be widely and commonly used in large quantities. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products.

Solar panels are divided into monocrystalline, polycrystalline and amorphous silicon. Most solar panels are primarily made of monocrystalline and polycrystalline materials.

Monocrystalline power generation panels are better. Monocrystalline power generation panels have high conversion efficiency, long lifee longer and better energy production on rainy days.

The difference between monocrystalline silicon and polycrystalline silicon lies in the arrangement of their atomic structure. Monocrystalline silicon is arranged in an orderly manner, while polycrystalline silicon is arranged in a disorderly manner.

Monocrystalline solar panels. : no pattern, Dark blue, almost black after encapsulation.

Polycrystalline solar panels: There are multi-color polycrystalline and less colorful polycrystalline patterns, such as the snowflake crystal pattern on the light blue snowflake-shaped iron sheet.

Which is better, monocrystalline silicon or polycrystalline silicon for solar panels?

Well, polycrystalline silicon. 1. Monocrystalline Silicon Polycrystalline silicon is a raw material used to make solar panels. 2. Silicon is an elementextremely abundant element on earth. It is present almost everywhere and can be considered inexhaustible. There is no shortage of raw materials for manufacturing silicon-based solar cells. 3. The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage should be stable. 4. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, and the photoelectric conversion efficiency is about 12%, which is slightly lower than that of monocrystalline silicon solar cells. . However, the manufacturing of the material is simple and convenient, consumes less energy, and the total production cost is low, so it has been greatly developed.

Single crystal has a high conversion efficiency and is expensive; polycrystalline has a low conversion efficiency and is goodn market.

There are many polycrystals in the domestic market, or they are all polycrystals.

The Japanese market is very popular recently, but Japan's requirements are very high and they are all monocrystalline. People's idea of ​​Japan is to do your best and do it right the first time. It has very high requirements for mitigation effectiveness, and we need to learn from that at home.

I think polycrystalline silicon and monocrystalline silicon solar panels are better than polycrystalline silicon.

1. Low cost

The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage is more stable. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells. Its effectivenessThe photoelectric conversion rate is about 12%, which is slightly lower than that of monocrystalline silicon solar cells. However, the material is easy to manufacture, saves energy. and the overall production cost is low, so there is a lot of development.

2. Beautiful craftsmanship

Single crystals are arranged in an orderly manner, while polycrystalline crystals are arranged in a disorderly manner. This is mainly determined by their processing technology. produced by casting methods, that is, directly pouring silicon into a crucible to melt and shape it, while the single crystal adopts the Siemens method to improve the Czochralski process.The structural reorganization process. To our naked eyes, the surface of monocrystalline silicon looks the same, while the surface of polycrystalline silicon appears to contain a lot of broken glass, making it sparkle.
