While most solar PV module companies are nothing more than assemblers of ready solar cells bought from various suppliers, some factories have at least however their own solar cell production line in which the raw material in form of silicon wafers is further processed and refined.
The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.
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.
How Does Solar Work? Solar manufacturing encompasses the production of products and materials across the solar value chain. While some concentrating solar-thermal manufacturing exists, most solar manufacturing in the United States is related to photovoltaic (PV) systems.
Those systems are comprised of PV modules, racking and wiring, power electronics, and system monitoring devices, all of which are manufactured. Learn how PV works. Read the Solar Photovoltaics Supply Chain Review, which explores the global solar PV supply chain and opportunities for developing U.S. manufacturing capacity.
The manufacture of PV racking systems varies significantly depending on where the installation will occur. Ground-mounted racking is made from steel, which is typically coated or galvanized to protect from corrosion and requires concrete foundations.
