i'm very interested in learning about photovoltaic cells, I've read in some sites already but they all describe it in very general way, can anyone tell me on detail how does it work?
thanks
thanks
Photovoltaic cells, also known as solar cells, are made up of layers of silicon that have been treated with certain chemicals. When sunlight hits these layers, it releases electrons from the silicon atoms, creating an electric current. This process is known as the photovoltaic effect.
Monocrystalline cells are made from a single crystal of silicon, giving them a uniform appearance and higher efficiency. Polycrystalline cells are made from multiple fragments of silicon, resulting in a less uniform appearance and slightly lower efficiency.
The efficiency of a photovoltaic cell refers to the percentage of sunlight that is converted into electricity. Higher efficiency cells will produce more electricity for a given amount of sunlight, making them more desirable for solar energy systems.
While sunlight is the primary source of energy for photovoltaic cells, they can still produce electricity on cloudy days. The cells are able to capture and use diffuse or indirect sunlight, although their efficiency may be reduced compared to sunny days.
Most photovoltaic cells have a lifespan of 25-30 years, although they can continue to produce electricity for even longer. With proper maintenance and care, they can last for decades and provide a reliable source of renewable energy.
