Amorphous silicon solar panels have the following significant advantages:
High photoelectric conversion efficiency
Amorphous silicon solar panels have a relatively high light absorption coefficient in the visible light band, especially within the range of 0.3 to 0.75 micrometers, where the absorption coefficient is one order of magnitude higher than that of monocrystalline silicon.
This enables amorphous silicon solar panels to absorb 90% of the useful solar energy with a very thin film (about 1 micron thick), thereby achieving a relatively high photoelectric conversion efficiency.
Although the photoelectric conversion efficiency of amorphous silicon solar panels is currently slightly lower than that of monocrystalline silicon and polycrystalline silicon panels, their performance is particularly outstanding under low-light conditions.
Low cost
The manufacturing cost of amorphous silicon solar panels is relatively low, mainly due to their simple manufacturing process and less consumption of silicon materials.
The process and equipment for preparing amorphous silicon are simple, with a low deposition temperature (about 200℃) and a short time, making it suitable for mass production.
Amorphous silicon solar panels can use inexpensive materials such as glass, stainless steel, and plastic as substrate materials, further reducing costs.
Light weight and thin thickness:
The silicon film thickness of amorphous silicon solar panels is only 1-2 microns, which is 1/500 of the thickness of monocrystalline silicon or polycrystalline silicon cells (about 0.5 millimeters). This makes amorphous silicon solar panels have the characteristics of light weight and thin thickness.
This feature makes amorphous silicon solar panels more convenient to transport, install and use, and is also more suitable for some occasions with strict requirements for weight and thickness.
Easy to form large-scale production capacity:
The core process of amorphous silicon solar panels is suitable for manufacturing large-area films without structural defects, and the production process can be fully automated.
By changing the gas phase composition or gas flow rate, PIN junctions and corresponding laminated structures can be easily achieved, which improves production efficiency and product quality.
Many varieties and wide applications:
Amorphous silicon solar panels are easy to integrate and can be designed with different powers, output voltages and output currents according to customer requirements.
Due to its high light absorption coefficient, amorphous silicon solar panels are suitable for making low-power power sources for indoor use, such as watch batteries and calculator batteries.
Amorphous silicon solar panels can also be made into flexible cells and used in some applications that require curved surface installation, such as building-integrated photovoltaic systems and wearable devices.
Insensitive to temperature changes
Amorphous silicon solar panels can still maintain a relatively high photoelectric conversion efficiency under high-temperature conditions, and are much less affected by temperature than crystalline silicon solar panels.
This gives amorphous silicon solar panels obvious advantages in the application of hot regions or high-temperature environments.
Green and environmentally friendly
The manufacturing process of amorphous silicon solar panels does not involve any environmentally polluting steps such as mining, crushing, painting and heat generation.
It has a long service life, and some of its materials can be recycled, featuring high environmental friendliness and sustainability.
Strong weather resistance
Amorphous silicon solar panels are more resistant to strong solar radiation such as ultraviolet rays, and have a longer service life and higher stability.
This enables amorphous silicon solar panels to maintain a good working condition even in harsh environments.
In summary, amorphous silicon solar panels have broad application prospects in the field of solar cells due to their advantages such as high efficiency, low cost, light weight, and ease of large-scale production.
