Polycrystalline
Polycrystalline silicon can be further divided into the following types:
a. Traditional Polycrystalline Silicon: Traditional polycrystalline silicon is polycrystalline silicon material grown using vapor-phase mixing and is typically used in the manufacture of standard photovoltaic cells. It has a lower production cost, but the crystal quality is slightly inferior to that of precision single-crystal silicon.
b. Sputtered polysilicon: Sputtered polysilicon is a polycrystalline silicon material produced under high temperature and pressure conditions. It has high electrical properties and low intracrystalline impurity content, making it suitable for the manufacture of high-efficiency solar cells.
c. Sputtered polysilicon: Sputtered polysilicon is a material produced by directly depositing polycrystalline silicon thin films on glass or other substrates using a spray coating process. It has low production costs and high production efficiency, and can be used in the manufacture of large-area solar cells and thin-film cells.
In general, polysilicon is mainly divided into three types: traditional polysilicon, sputtered polysilicon, and sprayed polysilicon. Each has its own advantages and disadvantages and is suitable for different applications and technical requirements. With the continuous development and innovation of technology, polysilicon will be further improved and diversified, providing more options for the manufacture of optoelectronic devices.
