Main uses and materials of solar panels

The main material of solar panels is monocrystalline silicon or polycrystalline silicon wafers. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 18%, and the highest reaches 24%.
This is the highest photoelectric conversion efficiency of all kinds of solar cells, but the production cost is so high that it cannot be used generally. due to monocrystalline silicon
It is generally packaged with tempered glass and waterproof resin, so it is durable and has a service life of up to 25 years.

The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower, and its photoelectric conversion efficiency is about 16%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is easy to manufacture, saves power consumption, and the total production cost is low, so it has been greatly developed. In addition, the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of cost performance, monocrystalline silicon solar cells are slightly better.

A solar panel is a device that directly or indirectly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect by absorbing sunlight.
The main material of solar panels is "silicon", but due to the high production cost, there are certain limitations in its widespread use. Compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly.
