Polycrystalline solar panels, also known as polysilicon or multi-silicon panels, are the most common type of solar panels used in residential solar installations. They are distinguished by their bluish color and distinct squareish cells, resulting from the process of melting multiple silicon fragments together to form the wafers for the panel.
Silicons form the heart and soul of solar panels. For polycrystalline panels, the use of less pure silicon slightly reduces the efficiency. That said, it should be noted that this variance is minimal and perhaps, not noticeable in daily use.
Basic polycrystalline silicon based solar cells with a total area efficiency of app. 5% has been fabricated without the involvement of anti-reflecting coating. This is a resonable result considering that comercial high efficiency solar cells have a con-version efficiency of about 22%, as outlined in chapter 1.
They look grainier and have a bluer coating than mono-Si cells because of the cell’s defective crystal structure. The conversion efficiency of poly-Si/mc-Si cells is presently over 21%, averaging between 14% and 16%. This should have explained the polycrystalline solar panel size.
The slabs of polycrystalline solar panels are created by melting several silicon shards together. The molten silicon vat used to make the polycrystalline solar cells is permitted to cool on the panel itself in this situation. The surface of these solar cells resembles a mosaic.
Polycrystalline panels have a limited amount of electron movement inside the cells due to the numerous silicon crystals present in each cell. These solar panels convert solar energy into power by absorbing it from the sun. Numerous photovoltaic cells are used to construct these solar screens.
