Polycrystalline Silicon Solar Cells

Polycrystalline silicon is the key feedstock in the crystalline silicon based photovoltaic industry and used for the production of conventional solar cells.

The photovoltaic industry however groups them into two distinct categories. Crystalline silicon c si used in traditional conventional wafer based solar cells. 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. That s because they don t go through the czochralski process. As a result polycrystalline solar panels have lower efficiency ratings than monocrystalline panels. Due to these defects polycrystalline cells absorb less solar energy produce consequently less electricity and are thus less efficient than monocrystalline silicon mono si cells.

For this reason they are called poly or multi crystalline. The electrons in each cell will have less space to move because of many crystals in a cell. High conversion efficiencies resulting. Because there are many crystals in each cell there is less freedom for the electrons to move.

What are polycrystalline solar panels. Polycrystalline silicon solar cells. Polycrystalline silicon solar cell panels are probably the easiest and most efficient to produce when compared to the monocrystalline variety. Polycrystalline panels sometimes referred to as multicrystalline panels are popular among homeowners looking.

For the first time in 2006 over half of the world s supply of polysilicon was being used by pv manufacturers. Polycrystalline solar cells are manufactured like monocrystalline panels a seed crystal is placed into. Polycrystalline silicon is a very promising material for the realization of low cost and efficient solar cells for terrestrial photovoltaic applications. 156mm 156mm thickness si 180um color blue efficiency.
