Polycrystalline Silicon Solar Panel

Polycrystalline silicon solar panel.

Polycrystalline silicon solar panel.

Because there are many crystals in each cell. Polycrystalline silicon or multicrystalline silicon also called polysilicon or poly si is a high purity polycrystalline form of silicon used as a raw material by the solar photovoltaic and electronics industry. To make the cells of polycrystalline panel fragments of silicon are melted together to form the wafers. Polycrystalline solar panels are less space efficient.

Polycrystalline phases are composed of a number of smaller crystals or crystallites. Usually polycrystalline silicon solar cells won t have the corners cut off of them so you won t see the large white spaces on the front of the panel that you see on monocrystalline panels. For this reason they are called poly or multi crystalline. As a result polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.

The electrons in each cell will have less space to move because of many crystals in a cell. Polycrystalline solar panels are also referred to as multi crystalline or many crystal silicon. Polycrystalline solar panel manufacturers melt multiple silicon fragments together to produce the wafers for these panels. Polysilicon is produced from metallurgical grade silicon by a chemical purification process called the siemens process.

An emerging alternative process of re. Polycrystalline solar panels are also made from silicon. Polycrystalline cell have efficiency of 20 4 and market share of about 54 9 of all solar panel market which is highest then any other technology of solar pannel. These panels are made of silicon.

This process involves distillation of volatile silicon compounds and their decomposition into silicon at high temperatures. Polycrystalline solar panelare also known as poly solar panel multi crystalline or many crystal silicon panel. Hence they are less efficient and durable. Polycrystalline solar panel tends to be less efficient offers 13 16 efficiency rate the purity level of silicon is lower as compared to monocrystalline solar panels.

However instead of using a single crystal of silicon manufacturers melt many fragments of silicon together to form the wafers for the panel. Polycrystalline silicon is a material consisting of multiple small silicon crystals. Polycrystalline solar panels along with other types of panels have been used in the generation of solar power for several years. Polycrystalline is little cost effective then monocrystalline technology and it have highest market share in all solar panel.
