how does solar energy work?
The main reason for solar panels to generate electricity is that the internal crystalline silicon is the most photovoltaic material. In terms of types, monocrystalline silicon has replaced polycrystalline silicon as the type with the best market share. In addition to these two materials, there are designs for crystalline silicon solar panels and multi-compound solar cells currently on the market. The following is a brief introduction to the characteristics of different materials.

1. Monocrystalline silicon solar panels
The conversion rate of monocrystalline silicon solar cells is about 15%-25%, which has a higher conversion rate than polycrystalline solar cells, and is the cell with the highest power generation efficiency. Because the monocrystalline silicon solar panel is a package design, the outer layer is covered with waterproof glass, and the analysis also uses a waterproof resin. Its life span is longer than the original ordinary solar panel, reaching 15-25 years. But its cost is also relatively high.

2. Polycrystalline silicon solar panels
Polycrystalline silicon and monocrystalline silicon have similar power generation principles, but the conversion efficiency is much lower.
Generally less than 20%. However, the production cost is lower, and the material is saved more. The service life is generally only about 60% of the single crystal module.

3. Amorphous silicon solar panels
Amorphous silicon solar panels first appeared in 1976. They were the earliest type of solar panels. Their efficiency could only reach about 10%, and they were not stable enough.

4. Multi-compound solar panels
This type of solar panel currently has many categories in the international market. Common solar panels are made of materials such as cadmium sulfide, gallium arsenide and copper indium selenium. However, these types of solar panels are suitable for scientific research, not suitable for industrialized batches. Production, low stability.

Many people may wonder whether solar panels can be placed on cars. In fact, this is not a concept. Many vehicles have allowed solar panels to be installed, such as buses and RVs. However, for ordinary private cars, it is because the models themselves are more expensive. Small, coupled with the fact that the demand for electricity is not particularly high, it is often relatively rare.
