Types of solar cell modules
1. Monocrystalline silicon solar cells
Monocrystalline silicon solar cells have a photoelectric conversion efficiency of around 17%, with the highest reaching 24%, which is the highest among all types of solar cells. However, their manufacturing cost is very high, preventing their widespread and common use. Because monocrystalline silicon is typically encapsulated with tempered glass and waterproof resin, it is robust and durable, and most manufacturers typically offer a 25-year warranty.
Monocrystalline flexible solar modules: Also known as flexible modules, these modules are flexible because they can be bent. The bending angle can reach 30 degrees. Solar cell modules (also called solar panels) are the core and most important component of a solar power system.
2. Polycrystalline silicon 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 significantly lower, around 15%. In terms of manufacturing cost, they are cheaper than monocrystalline silicon solar cells due to simpler material manufacturing, lower energy consumption, and lower overall production costs, thus leading to their widespread adoption. However, polycrystalline silicon solar cells also have a shorter lifespan than monocrystalline silicon solar cells. From a performance-price ratio perspective, monocrystalline silicon solar cells are slightly better.
3. Amorphous silicon solar cells
Amorphous silicon solar cells, a new type of thin-film solar cell that emerged in 1976, are manufactured using methods completely different from those of monocrystalline and polycrystalline silicon solar cells. The process is greatly simplified, requiring very little silicon material and resulting in lower power consumption. Its main advantage is its ability to generate electricity even in low-light conditions. However, the main problem with amorphous silicon solar cells is their relatively low photoelectric conversion efficiency, which is around 10% at the international advanced level, and it is also not very stable, with its conversion efficiency decreasing over time.
