Polycrystalline.

In polycrystalline solar cells each PV cell is made of multiple silicon crystal fragments that are melded together during manufacturing. ;In addition, polycrystalline solar cells tend to have a blue hue instead of the black hue of monocrystalline cells.

They were the first solar cells to be developed when the industry started in the 1980s. Most interestingly, polycrystalline cells do not undergo the same cutting process as the monocrystalline cells. Instead, the silicon is melted and then poured into a square mould. This is what creates the specific shape of the polycrystalline.

One of the benefits of this process is that the solar cells become much more affordable. This is because hardly any silicon is wasted during the manufacturing process. However, they are less efficient than monocrystalline solar cells, and also require a lot more space. This is due to the fact that they have lower levels of purity than the single crystalline cell models.

Polycrystalline also has a lower tolerance for heat than monocrystalline. This means that they are unable to function as efficiently in high temperatures. This can be a massive disadvantage in areas with hot climates.

Polycrystalline silicon is normally considered less efficient than single-crystal silicon. On the other hand, polycrystalline silicon devices are less expensive to produce. The casting process is the most common means of producing polycrystalline silicon on a commercial scale.

Polycrystalline solar cells are cheaper than monocrystalline cells, however, they are less efficient and aren’t as aesthetically pleasing.
