What is the difference between amorphous silicon, monocrystalline silicon and polycrystalline silico

1. Difference in appearance

The four corners of monocrystalline silicon cells are arc-shaped, and there is no pattern on the surface;

The four corners of polycrystalline silicon the cells are square. The surface has a pattern similar to ice flowers;

Amorphous silicon cells are what we usually call thin-film modules. Unlike crystalline silicon cells where the grid lines are visible, the surface is also clear. and smooth as a mirror;

2. The above usage differences

For users, there is not much difference between monocrystalline silicon batteries and polycrystalline silicon batteries. Their lifespan and stability are very important. GOOD.

Although the average conversion efficiency of monocrystalline silicon cells is about 1% higher than that of polycrystalline silicon cells, givené that monocrystalline silicon cells can only have a quasi-square shape (all four sides are arc-shaped). ), they cannot be used when forming solar panels. If there is a problem, part of the area will not be filled with polysilicon, so there is no such problem. Their advantages and disadvantages are as follows:

< p>Crystalline silicon modules: The power of a single module is relatively high. Under the same floor space, the installed capacity is higher than that of thin-film modules. However, the components are thick and fragile, have poor high temperature performance, poor low light performance, and high annual attenuation rate.

Thin film module: The power of a single module is relatively low. However, it has high power generation performance, good high temperature performance, goodlow-light performance, low shadow-blocking power loss, and low annual attenuation rate. It has a wide application environment, beautiful appearance and environmental protection.

3. Differences in manufacturing processes

The energy consumed in the manufacturing process of polycrystalline silicon solar cells is approximately 30% lower than that of monocrystalline silicon solar cells;

3 . p>Therefore, polycrystalline silicon solar cells cells account for a large part of the world's total solar cell production and the manufacturing cost is lower than that of monocrystalline silicon cells, therefore the use of polycrystalline silicon solar cells Polycrystalline silicon will be more energy efficient and environmentally friendly. ;

There are many ways to use amorphous silicon solar cells, including p-chemical depositionplasma-assisted vapor hase, reactive sputtering, glow discharge, electron beam evaporation and thermal decomposition of silane.

Polycrystalline silicon is good.

Different appearance: Monocrystalline photovoltaic panels are darker, there will be gaps between cells and the whole panel will look like white dots. Polycrystalline photovoltaic panels are bluish in color. There are no gaps between cells and the overall appearance is consistent. In relation to their electricity production capacity. The power generation capacity of a single chip is larger.

Different efficienciescited:The attenuation efficiency of polycrystalline at high temperature is much lower than that of single crystal. Therefore, the most commonly used photovoltaic panels on the market are polycrystalline silicon wafers. Like many residential users, considering the decay time of energy production photovoltaic panels, they also choose polycrystalline photovoltaic panels.

Precautions for solar panels

There are currently two types of The main solar technologies are photovoltaics, which uses arrays of cells to convert sunlight into electricity; and thermal, which uses sunlight to heat water or air for internal use.

Be aware that if your home uses a lot of energy to heat your home, or if you live in an area where heating fuel is expensive compared to electricityity, then a solar thermal investment can be a better way to break even? However, solar thermal is rare in homes, so finding qualified installers can be difficult.
