Silicon wafers are by far the most widely used semiconductors in solar panels and other photovoltaic modules. P-type (positive) and N-type (negative) wafers are manufactured and combined in a solar cell to convert sunlight into electricity using the photovoltaic effect.
Solar cells are connected to form larger power-generating units known as solar panels. The bandgap is a crucial property of PV semiconductors as it indicates the wavelengths of light that the material can absorb and convert into electrical energy.
Both polycrystalline and monocrystalline solar panels use wafer-based silicon solar cells. The only alternatives to wafer-based solar cells that are commercially available are low-efficiency thin-film cells. Silicon wafer-based solar cells produce far more electricity from available sunlight than thin-film solar cells.
Silicon isn’t the only semiconductive material used to make solar cells. But it is the most commonly used by far. Over 90% of solar panels sold today rely on silicon wafer-based cells. Silicon is also used in virtually every modern electronic device, including the one you’re reading this on… Unless you printed it out.
Semiconductor devices are key in solar technology. They use special properties to change sunlight into electricity. At the core of a solar panel, the semiconductor junction turns light into power, showing the magic of solar energy. Today, silicon is used in almost all solar modules because it’s dependable and lasts long.
About 95% of solar panels on the market today use either monocrystalline silicon or polycrystalline silicon as the semiconductor. Monocrystalline silicon wafers are made up of one crystal structure, and polycrystalline silicon is made up of lots of different crystals.
