Solar cells, also known as photovoltaic (PV) cells, are devices that convert sunlight directly into electricity through the photovoltaic effect. They are made primarily from semiconductor materials like silicon. When sunlight hits the solar cell, it excites electrons in the semiconductor material, causing them to flow and generate electric current. Solar cells are the building blocks of solar panels, which are assembled into larger arrays to produce power for residential, commercial, and industrial applications. Over the years, the efficiency of solar cells has significantly improved, making solar power a more viable and increasingly cost-effective alternative to traditional fossil fuels. Research continues into developing new materials and technologies, such as perovskite solar cells and multi-junction solar cells, to enhance performance and reduce production costs, further driving the adoption of solar energy globally.
