Polysilicon is one of the most essential elements used in the energy industry. It is also called as Poly-Si and is known for its high purity. It is used as a raw material by the electronics and solar photovoltaic industry. You might have different solar modules providing energy, and most of these solar modules use this material.

Overview

The Polysilicon is different from standard Silicon as regular Silicon is just a non-metallic element with an atomic number 14, and it has an atomic weight of 280855. But if we talk of this element, then there are many things you should consider.

This is the polycrystalline form of Silicon which is more useful than the Silicon. It is used in many solid-state devices, and it is also used as the gate materials, and it is firmly resistant to heat. The self-alignment is also possible in this form of Silicon.

It is produced from the metallurgical grade Silicon with the process known as the Siemens process, and this process easily removes the volatiles silicon compounds with the help of distillation. The core structure of this material is composed of many smaller crystals, and it consists of a lot of small silicon crystals.

Applications and uses

There are many uses of polycrystalline form silicon, and here are some mentioned:

• This material is used in different semiconductor applications.
• It also has much application in VLSI manufacturing.
• This material is also used as the gate electrode material for the MOS devices.
• It is also used as the gate materials as it doesn’t melt quickly.
• The self-alignment is possible in this material.

The electrical conductivity of the gate can be increased easily by the deposition of metal like tungsten or a metal silicide like the one obtained with tungsten. The filing needs to occur over the gate.

The Solar Module

The Polycrystalline Solar Module or panel is one of the most popular product manufactured by the solar energy industry. These panels are used by many people due to their cost-effectiveness and durability. They are also known as the multi-crystalline solar panels.

There is also another kind of silicon solar panels known as the Monocrystalline Silicon Solar Panels, and they are of black color. They are made of the cylindrical silicon ingots, and they also have higher efficiency. Here the efficiency is high due to the purity of Silicon and they also need a smaller installation area.

Polycrystalline Solar Module is different from mono in many ways. In Poly-Si, the melted Silicon isn’t used purely as it is then poured into a squared mold. This is also cheaper and much simpler than the monocrystalline, and silicon waste is very much redundant.

It is essential to identify the type of module you need for your place. You can locate this by recognizing the kind of power you want. Although Poly-Si has low efficiency and performance, it can be increased quickly if operating temperature increases. So if you live in a suburban area, then Poly-Si would be the best choice for you.
