Silicon wafers come from cutting silicon ingots into thin discs. The ingots start as melted silicon that is cooled and solidified. Special tools, like wire saws, are then used for cutting. This makes the wafers thin and even, which is important for making solar cells later.
Monocrystalline silicon cells can absorb most photons within 20 μm of the incident surface. However, limitations in the ingot sawing process mean that the commercial wafer thickness is generally around 200 μm. This type of silicon has a recorded single cell laboratory efficiency of 26.7%.
In the field of solar energy, monocrystalline silicon is also used to make photovoltaic cells due to its ability to absorb radiation. Monocrystalline silicon consists of silicon in which the crystal lattice of the entire solid is continuous. This crystalline structure does not break at its edges and is free of any grain boundaries.
The production process from raw quartz to solar cells involves a range of steps, starting with the recovery and purification of silicon, followed by its slicing into utilizable disks – the silicon wafers – that are further processed into ready-to-assemble solar cells.
The key components in solar PV manufacturing include silicon wafers, solar cells, PV modules, and solar panels. Silicon is the primary material used, which is processed into wafers, then assembled into solar cells and connected to form solar modules.
The creation of photovoltaic panels centers around turning crystalline silicon into solar cells. These cells are part of large solar projects worldwide. Learning about the solar cell manufacturing process shows how we’ve advanced from the first commercial solar panel to today’s advanced modules. These modules power our homes and cities.
