The first solar panels based on polycrystalline silicon, which also is known as Poly silicon (p-Si) and multicrystalline
silicon (mc-Si), were introduced to the market in 1981. Unlike Mono Crystalline-based solar
panels, Polycrystalline solar panels do not require the Czochralski process. Raw silicon is melted and
poured into a square mold, which is cooled and cut into perfectly square wafers. These Kind Of Solar Cells
In Normally In Color Blue. As a Picture Below
- The efficiency of polycrystalline-based solar panels is typically 13-15%. Because of lower
silicon purity, polycrystalline solar panels are not quite as efficient as Mono Crystalline solar
- You need to cover a larger surface to output the same electrical power as you would with a solar
panel made of Mono Crystalline silicon.
- Mono Crystalline and thin-film solar panels tend to be more aesthetically pleasing since they have a
more uniform look compared to the speckled blue color of polycrystalline silicon.
