What is the difference between monocrystalline silicon and polycrystalline silicon in photovoltaic p

The difference between monocrystalline silicon and polycrystalline silicon in photovoltaic panels:

1. Different conversion efficiencies

The current photoelectric conversion efficiency of monocrystalline silicon solar cells is 17%. About 24% is the highest, which is currently the highest photoelectric conversion efficiency among all types of solar cells. 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 15%. .

2. The manufacturing cost is different

The manufacturing cost of monocrystalline silicon is so high that it cannot be widely and commonly used in large quantities. In terms of cost ofproduction, it is cheaper than monocrystalline silicon solar cells. The material is easy to manufacture, saves energy, and the overall production cost is low, so it has been widely developed.

3. Difference in Lifespan

The lifespan of polycrystalline silicon solar cells is also shorter than that of monocrystalline silicon solar cells. Monocrystalline silicon is usually packaged with tempered glass and waterproof resin. , so it is strong and durable, with a lifespan generally of 15 years and up to 25 years. . In terms of performance-price ratio, monocrystalline silicon solar cells are slightly better.

Detailed information:

< p>Monocrystalline silicon is widely used in solar cells. High purity single crystal silicon is a semiconductor material imimportant. Today, with the rapid development of photovoltaic technology and micro-semiconductor inverter technology, solar cells produced from monocrystalline silicon can directly convert solar energy into light energy, thus realizing a step toward the beginning of the world. green energy revolution.

Characteristics of monocrystalline silicon solar cells:

High photoelectric conversion efficiency and high reliability;

2. Advanced diffusion technology ensures uniformity of all parts of the chip. conversion efficiency;

3. Using advanced PECVD film forming technology, a dark blue silicon nitride anti-reflective film is plated on the surface of the battery, with uniform and beautiful color;

< p>4. Use high quality metal paste to make the backfield and electrodes to ensure good conductivity.

Determine the screen layout, draw the basic outline, etc.

1. Determine image layout: Decide which scene to display, such as a roof, solar power plant, or any other location where photovoltaic panels are installed. Consider angles and viewing angles and choose one that clearly displays a photovoltaic panel array.

2. Draw the basic outline: Use a light pencil or thin line to draw the general shape and layout of the PV panels. You can refer to photos of actual photovoltaic panels or use simple geometric shapes to represent each photovoltaic panel.
