Solar photovoltaic cell manufacturing has come a long way in recent decades. The raw silicon materials are converted into ingots, sliced into wafers, fabricated into cells, assembled into panels, and tested for safety and performance. While the basic manufacturing process is well established, there are always opportunities for improvement.
At the heart of every solar panel lies the photovoltaic (PV) cell, the unsung hero responsible for transforming sunlight into electricity. These cells, typically made from silicon, a semiconductor material, are the workhorses that drive the entire process. But how does this conversion happen? Imagine a silicon atom like a miniature solar system.
At the core of each solar panel are numerous solar cells, small devices made primarily from silicon. These cells are where the magic happens—where sunlight is transformed into electrical energy.
The Powerhouse: The Photovoltaic Cell At the heart of every solar panel lies the photovoltaic (PV) cell, the unsung hero responsible for transforming sunlight into electricity. These cells, typically made from silicon, a semiconductor material, are the workhorses that drive the entire process.
To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
Solar panels are manufactured by purifying silicon from quartz sand, collecting it into solid rocks, and then melting these rocks into cylindrical ingots using a steel cylindrical furnace. What is the raw material of solar panels? The raw material of solar panels is primarily silicon, a component abundantly found in natural beach sand.
The production journey of a silicon solar cell begins with sand, or to be precise, quartz. After extraction, the quartz is then heated in a furnace with carbon to produce metallurgical grade silicon. This silicon is then purified further and melted down before being formed into a large crystal – a process known as Czochralski process.
