fotovoltailiseid

Fotovoltailised, also known as photovoltaic cells or solar cells, are devices that convert light energy, typically from the sun, into electrical energy. They are a key component of solar panels and are widely used in various applications, including residential, commercial, and industrial settings. Photovoltaic cells operate on the principle of the photovoltaic effect, where photons from light excite electrons in a semiconductor material, generating an electric current.

The most common type of photovoltaic cell is made from silicon, which can be either monocrystalline or polycrystalline. Monocrystalline cells are made from a single crystal of silicon and are known for their high efficiency and durability. Polycrystalline cells, on the other hand, are made from multiple crystals and are generally less efficient but more cost-effective. Other materials, such as cadmium telluride (CdTe) and copper indium gallium selenide (CIGS), are also used in photovoltaic cells, offering different trade-offs in terms of efficiency, cost, and environmental impact.

Photovoltaic cells are typically arranged in modules or panels, which can then be combined into larger arrays to generate significant amounts of electricity. These solar panels can be installed on rooftops, in open fields, or even integrated into building materials. The efficiency of photovoltaic cells refers to the percentage of sunlight that is converted into usable electrical energy. Advances in technology continue to improve the efficiency and reduce the cost of photovoltaic cells, making solar energy an increasingly viable and sustainable source of power.
