Solar cells, also known as photovoltaic cells, convert light energy directly into electrical energy. They are made primarily from semiconductor materials, with silicon being the most common. When sunlight strikes the surface of a solar cell, it excites electrons in the semiconductor material, creating an electric current.
Let’s delve deeper into the world of photovoltaics and explore the intricate workings of solar panels explain by NFC 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.
Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)
That said, the rate at which solar panels generate electricity varies depending on the amount of direct sunlight and the quality, size, number and location of panels in use. Even in winter, solar panel technology is still effective; at one point in February 2022, solar was providing more than 20% of the UK’s electricity.1
The solar industry has developed high-tech, anti-reflective coatings and ultra-transparent glass to improve panel efficiency and, in fact, solar panels are less reflective than many common building features, such as windows. When it’s not sunny, how will we have enough clean energy to power the country?
Also, the number of solar panels in a solar system influences the amount of energy the whole solar power system generates. Semiconductors are at the heart of solar panels, i.e. solar energy systems. They come in a variety of combinations, depending on the material they are made of and their efficiency.
